Remove unused internal helper _FSGetHostname

Since we build with -export-symbols-regex '^FS.*', it wasn't available
to callers outside libFS, and was never called by anything inside libFS.

Xtrans provides it's own exact copy of this function, which gets
the name _FSTransGetHostname when built in libFS, nothing in libFS
outside the Xtrans code calls a gethostname() function.

Flagged by cppcheck 1.62:
[FSlibInt.c:1060]: (style) The function '_FSGetHostname' is never used.
