xfsprogs: avoid dot-directories when configuring

The "find" command used in the configure script to find localized files searches through directories (including .git and .pc) that really should be ignored. Change it so it skips over these directories.

I think it's reasonable to assume any such "dot directory" should be ignored, so this change skips any directory at the top level whose name begins with ".".

Note that I found an odd anomaly in "find". If you do not supply the "-print" argument, the pruned directory names show up in the output. Supplying "-print" does not include them (and that's what we want).
