BSD refinements

Make it easier to compile flashrom under NetBSD and DragonFlyBSD:
 - Use /usr/pkg/ as prefix for includes and linking
 - Use pciutils as include path for the right(tm) libpci

Also, fix date handling in getrevision.sh to work with the various formats for
invoking 'date'. This also uses svn's info --xml output instead of the regular one.

Corresponding to flashrom svn r1742.
