Added extended wildcard support when specifying --run-subtest.

Wildcard format is as specified in rfc3977 and the uwildmat() implementation
is taken from libinn.
See https://tools.ietf.org/html/rfc3977#section-4

 for a description of
allowed wildcard expressions.

v2: Use comma as list separator (Ville Syrjala)
