Use RMQ_ERLC_OPTS for ERL_COMPILER_OPTIONS

[lukebakken]

This is a follow-up to commit 93db480

I'm also looking into why the two *_sql_* files are modified on every build...

Should we tweak RMQ_ERLC_OPTS defaults to include deterministic?

[lukebakken]

RMQ_ERLC_OPTS already does! This change is so that if someone wants to ensure deterministic is not used anywhere (i.e. you're going to re-compile code in the rabbit app in the erl shell), they run this:

make RMQ_ERLC_OPTS=''
