Add fallocate and use it instead of posix_fallocate if possible (#398)
fuse.ko has supported FALLOC_FL_KEEP_SIZE and FALLOC_FL_PUNCH_HOLE at this
moment and more modes may be supported in the future.
fallocate(2) supports modes while posix_fallocate(2) does not, so this
makes lo_fallocate use fallocate(2) instead.
