This also bumps the libc version to get MFD_ALLOW_SEALING.

Using minijail_fork removes the need to manage user and pid namespace
explicitly in crosvm and removes some parent/child synchonization
requirements too.

ab839e293d fix dependency versions and add Cargo.lock
To ensure dependencies don't accidentally get updated, their versions are
fixed using the equals constraint. The Cargo.lock file is also checked in
so that the registry won't need to be downloaded by cargo.

These changes are needed so that the crosvm ebuild will not need to
download anything outside of its list of source packages.
