perf parse-events: Fixes relating to no_value terms

Browse Source 
A term may have no value in which case it is assumed to have a value
of 1. It doesn't just apply to alias/event terms so change the
parse_events_term__to_strbuf assert.

Commit 99e7138eb7 ("perf tools: Fail on using multiple bits long
terms without value") made it so that no_value terms could only be for a
single bit. Prior to commit 64199ae4b8 ("perf parse-events: Fix
propagation of term's no_value when cloning") this missed a test case
where config1 had no_value.

Fixes: 64199ae4b8 ("perf parse-events: Fix propagation of term's no_value when cloning")
