package.bbclass: introduce KEEP_GNU_DEBUGLINK

Currently we're keeping .gnu_debuglink section in files after stripping them.
It makes binaries from successive builds a bit different, which is not good
in situations where you want them to be exactly the same (identical checksums).

So, introducing KEEP_GNU_DEBUGLINK which can be set to zero to disable this
behavior and get identical result on successive builds for most of the
packages.
