[Bug translator/2643] probe point wildcard expansion excessively optimistic

[fche at redhat dot com]

The patch for bug #2433 awakened a latent bug in the translator that expands
probe point wildcards.  The same problem appears with this case:

probe a.a.a = begin { }
probe a.b = begin { }
probe a.*.a  { }

The wildcard should expand to "a.a.a" only, but since it proceeds naively one
component at a time and lacks lookahead, it also expands to "a.b.a".

One quick hack as a workaround until the real fix is to add back some dummy
probe aliases for the two recently deceased.

probe syscall.exit.return = end {}
probe syscall.exit_group.return = end {}
