/usr/include/linux/fs.h:50:8: error: redefinition of 'struct file_clone_range'

was caused by btrfs.h gaining an include of linux/fs.h,
which clashed with QEMU's workaround for glibc compat
with linux/mount.h. GLibc huas fixed their sys/mount.h
so we can drop the QEMU workaround, thus fixing the
btrfs.h problem.
