[PATCH v2] contrib/plugins/execlog: Fix compiler warning

[Yao Xingtao]

1. The g_pattern_match_string() is deprecated when glib2 version >= 2.70.
   Use g_pattern_spec_match_string() instead to avoid this problem.

2. The type of second parameter in g_ptr_array_add() is
   'gpointer' {aka 'void *'}, but the type of reg->name is 'const char*'.
   Cast the type of reg->name to 'gpointer' to avoid this problem.

compiler warning message:
