devtool: update-recipe: fix handling of compressed local patches

It is possible to use gzip or bzip2 to compress patches and still refer
to them in compressed form in the SRC_URI value within a recipe. If you
run "devtool modify" on such a recipe, make changes to the commit for
the patch and then run devtool update-recipe, we need to correctly
associate the commit back to the compressed patch file and re-compress
the patch, neither of which we were doing previously.

Additionally, add an oe-selftest test to ensure this doesn't regress in
future.

Fixes [YOCTO #8278].
