lib/igt_core.c: Expand --run-subtest functionality.

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)
support both ^ and ! as not operators (Dave Gordon)

v3: Updated to use uwildmat() (Dave Gordon)
