Add statx support
This commit adds libfuse support for FUSE_STATX requests on
linux distributions.
Currently, statx is only supported on linux. To make the interface a
ergonomic as possible (eg using native 'struct statx' vs 'struct
fuse_statx'), this implementation gates the 'struct statx' changes
by #ifdef linux.
