trace: Only permit explicit prefix matching for functions

Browse source 
The matching code currently only tests whether the prefix of a function
matches. Make this more strict by ensuring that the function name is not
longer.

However, as this breaks some tests (due to inlining), add the ability to
do an explicit prefix match by appending a '*' to the function name. Use
this to change the eap_eke_prf match to eap_eke_prf_* in order to match
one of the actual implementations.
