libpod: Move uses of unix.O_PATH to container_internal_linux.go

The O_PATH flag is a recent addition to the open syscall and is not
present in darwin or in FreeBSD releases before 13.1. The constant is
not present in the FreeBSD version of x/sys/unix since that package
supports FreeBSD 12.3 and later.

[NO NEW TESTS NEEDED]
