Extend cover.erl source search
Commit 29231033 made cover fall back to compile info if source was not found in pwd or ../src. This isn't sufficient for source that lies in subdirectories of ../src when beams and source have been moved since compilation (eg. install of some OTP applications), so first try finding source relative to the beam directory. For example, given a beam path /installed/path/to/app-1.0/ebin/root.beam and a source path /compiled/path/to/app/src/subdir/root.erl then look for /installed/path/to/app-1.0/ebin/../src/subdir/root.erl before the source path.
