[Bug translator/10102] optional probe points should silently accept "probe point mismatch" errors

Thanks for that. I see a slightly different variant of this that seems a bit
harder to solve (at least, I didn't immediately see how it could be solved,
maybe someone else does see an easy solution):

$ stap -e 'probe process("/does/not/exist").function("main") ?, never { log
("process does exist"); }'
semantic error: libdwfl failure (missing process /does/not/exist i686
debuginfo): No such file or directory while resolving probe point
process("/does/not/exist").function("main")?

This probably needs a similar change in setup_user(), but we don't have the
probe location at that point, and setup_user() is called in a couple of
different situations (not all of which can silently fail).
