triggerhappy: bump PKG_REV to fix input header creation

Current configuration creates empty evtable_*.h header which makes all
the input event appear as "Unknown (null) event".

The maintainer of the project submitted a patch to fix this issue:
https://github.com/wertarbyte/triggerhappy/commit/7e5abc6

Thanks to this version bump, the old OpenWRT patch can be removed.
