perf probe: Handle gracefully some stupid and buggy line syntaxes

Currently perf probe doesn't handle those incorrect syntaxes:

   $ perf probe -L sched.c:++13
   $ perf probe -L sched.c:-+13
   $ perf probe -L sched.c:10000000000000000000000000000+13

This patches rewrites parse_line_range_desc() to handle them.

As a bonus, it reports more useful error messages instead of: "Tailing
with invalid character...".
