Subject: [PATCH] libarchive: Do not include sys/mount.h when linux/fs.h is
 present

These headers are in conflict and only one is needed by
archive_read_disk_posix.c therefore include linux/fs.h if it exists
otherwise include sys/mount.h

It also helps compiling with glibc 2.36
where sys/mount.h conflicts with linux/mount.h see [1]
