lib/oe/patch: prevent applying patches without any subject
* this was discovered with
$ devtool finish --force-patch-refresh
where it was removing some patches and replacing them with
patch in filename called "patch:"
e.g. this .patch file:
https://github.com/OSSystems/meta-browser/blob/
311067d2d8a50cee5c836892606444f63f2bb3ab/dynamic-layers/rust-layer/recipes-browser/firefox/firefox/fixes/fix-camera-permission-dialg-doesnot-close.patch
confuses devtool which results to create new .patch file called "patch:"
$ devtool finish --force-patch-refresh firefox meta-browser

this looked like incorrect parsing of the git format-patch
files exported from workspace/sources (the git format-patch
version of fix-camera-permission-dialg-doesnot-close.patch
starts like this:

Subject: [PATCH 08/34] %% original patch:
fix-camera-permission-dialg-doesnot-close.patch
so first I've modified GitApplyTree.extractPatches() to be able to
parse the original patch name correctly even in this case where subject
is wrapped, but then it still wasn't right, because we ended with
correctly named .patch file, but all we could use for Subject line
was the name of the original .patch file (instead of the Subject
from metadata commit which introduced this .patch files as some other
.patch files get when refreshed with devtool.
In the end the issue happens even sooner in GitApplyTree.prepareCommit()
where it correctly found the Subject from metadata commit, but then
didn't apply it when there weren't any other outlines from patch headers.
