Use the off64_t versions of libc file functions.
There is no Rust libc crate equivalent of the C _FILE_OFFSET_BITS and
related defines, so we have to use the Linux-specific *64 variants
explicitly.
This extends the size of file offsets to 64 bits instead of 32 on
platforms with 32-bit userspace.
(It also fixes the recently introduced check for non-LFS functions in
ChromeOS - see b/201531268 for details.)

The 9p lcreate operation takes a directory fid as input and creates a
file in that directory; when the operation completes, the same fid
becomes a reference to the newly-created file. We updated the internal
self.fids structure's file and path fields to point to the new file, but
we neglected to update the filetype field, which would remain as the
original FileType::Directory.
This caused an issue with commit 53cd18e062 ("p9: use *at() functions
for set_attr"), since that change causes set_attr requests to validate
the filetype is not a directory when attempting to set its length.

Use fchmodat(), fchownat(), and utimensat() to implement the SET_ATTR
request rather than using the non-'at' variants of these functions.
These can operate on a file descriptor path using the /proc file handle
and "self/fd/N" filename to modify the attributes of a file without
actually opening it, which means we can avoid problems like not being
able to open a read-only file with O_RDWR, which happened previously
with chmod requests.
This means we don't need to open the file at all, except in the case of
a request that needs to set the size, since there is no equivalent
truncateat() function.

We originally removed it because we had frequent merge conflicts
and all downstream projects were doing their own pinning already.
We also had CI issues because ChromeOS changes could trigger
Cargo.lock changes in crosvm back then.
The new Cargo.lock format should ease the merge conflicts and we
no longer have issues with external changes triggering changes
in our Cargo.lock. So let's bring it back in.
This will allow us to judge the impact of changing third party
dependencies and gives us a chance to implement a special
review process.

crosvm is switching the import style to use one import per line.
While more verbose, this will greatly reduce the occurence of merge
conflicts going forward.
Note: This is using a nightly feature of rustfmt. So it's a one-off
re-format only. We are considering adding a nightly toolchain to
enable the feature permanently.
