misc: use g_regex_match() for simplicity

This CL converts a few g_regex_match_full() expressions to their
equivalent g_regex_match() in order to simplify the code, i.e.

  g_regex_match_full (regex, str, strlen (str), 0, 0, &match_info, NULL)

is equivalent to:

  g_regex_match_full (regex, str, -1, 0, 0, &match_info, NULL)

or simply:

  g_regex_match (regex, str, 0, &match_info)
