swig: update swig recipe to match meta-oe
swig: update swig recipe to match meta-oe

The recipe keeps 3.0.5 and adds the relpath fixes for swig native that works
correctly. It also adds a patch for finding pcre using pkg-config. The only
difference with the upstream version is the explicit enabling of javascript &
version upgrade to 3.0.5
