example/passthrough: support fspacectl()
FreeBSD 14 introduced a new system call, fspacectl().
Currently, it supports one operation mode, SPACECTL_DEALLOC,
which is functionally equivalent to Linux fallocate() with
FALLOC_FL_KEEP_SIZE|FALLOC_FL_PUNCH_HOLE flags.
fspacectl() calls with SPACECTL_DEALLOC is supported on FUSE
filesystems via FUSE_FALLOCATE with the aforementioned flags.
