linux: remove Pathname stdlib dependency

The File.readlink has been available since the earliest SVN import
of Ruby from Jan 16 1998.  There's no reason to load the Pathname
class here since we don't do any further pathname manipulation.

So avoid loading the extra .so here and creating extra objects.
