wiringpi: Bump SRCREV

Update wiringpi to latest revision. Due to a refactoring of the build
procedure in wiringpi the integration patch 'makefile-install.patch'
didn't apply anymore. While migrating that patch it was simplified and
generated using 'git format-patch' instead, to make it easier to maintain
the patch in the future.

[Support #60]
