Message:

IPRT/fs-posix.cpp: Update RTFsQueryType() to use statvfs(2) instead of
stat(2) on Solaris. All RTFsQueryType() calls reference paths under
$HOME but Solaris 11 defaults to loopback mounting home directories
which means stat(2) always returns "lofs" so use statvfs(2) to get
the underlying file system type instead.
