Fix get_filename_component(... REALPATH) work dir 

The commit "Fix get_filename_component ABSOLUTE mode" broke REALPATH
treatment of relative paths because it stopped storing the absolute path
in local variable 'filename'.  This commit fixes the call to GetRealPath
to use the proper local variable and adds a test.
