posix: do not use fstat in isowner

The fstat function was undefined, but never used since a stat object
was always passed in the optional st argument. Passing st is now
mandatory.

This bug crept in when util was split up into posix and windows
modules. The fstat function is still defined in util, but importing it
into posix would create an import cycle which seems unnecessary.
