Subject: [PATCH v2] scripts/tags.sh: Tag timer definitions

For timer definitions like
DEFINE_TIMER(mytimer, mytimer_handler);
ctags generates tags `DEFINE_TIMER` and skips `mytimer`
because it doesn't expand the DEFINE_TIMER macro.

Configure ctags to generate tag for `mytimer`
ans skip the `DEFINE_TIMER` tag in such cases.
