On trogdor devices, fstatfs64 is not used. Instead, 32bit
fstatfs is used. We need to add both to all 32bit Arm
policy files which were originally determined to be
problematic.
This adds fstsatfs to all 32bit Arm policy files which
were modified for the original glibc security change.
Additionally, this commit sorts the syscalls lexicographically
if the policy file was already sorted.

At present, libraries which use glibc to dynamically load
shared libraries do not have fstafs in their seccomp policies.
A change in glibc will force all systems which load shared
libraries to call the fstatfs or fstatfs64 syscall.
Without the call, crosvm will not start when running
crostini/android tests.

The libminijail version in AOSP complains when there are multiple entries for
the same system call, which was the case for virtio-fs's policy.

Fds created via dup don't share file descriptor flags with the original
fd, which means that they don't have the FD_CLOEXEC flag set. Use
fcntl(F_DUPFD_CLOEXEC) so that this flag gets set for the duplicated fds
as well.

glibc 2.32 is using clock_gettime/64 on some arm boards
when gettimeofday is used. In addition, support 64-bit
variants of the time syscalls for use with glibc 2.32.
