btrace: add format argument to supports_btrace

Browse source 
Add a format argument to the various supports_btrace functions to check
for support of a specific btrace format.  This is to prepare for a new
format.

Removed two redundant calls.  The check will be made in the subsequent
btrace_enable call.
