bitbake: bb/utils: extend which() so it can look for just executables

Normally bb.utils.which() is used by the unpack code to find a file in a variety
of places, but it is useful as a slightly more powerful version of os.which().

Support this by allowing it to only return matches which are executable files,
instead of just the first filename that matches.
