providers: properly generate whitelist patterns from test plan's include
Whitelist qualifiers are generated with a code like:
for pattern in pattern_list
The pattern_list that was supplied was (in case of 'guessing whitlist from a
test plan') test_plan.include... which is a string!
That meant that str was treated like a list, and for longer include fields,
many thousands of those regex qualifiers were constructed. Aweful!
This patch repairs how those patterns are generated by parsing include field,
enveloping them with a historical ^ and $, and pushing them to the whitelist.
The result is 25% faster plainbox spool up.

state: defer recompute readiness till all units are added (adding whole prov)
There's no point in computing readiness every time new unit is added, not doing
so reduces plainbox startup with a typical set of jobs (~1k) by 15% \o/

For a typical set of providers (~1k of jobs) it gives ~5% wall time decrease
in parts that are always run on startup of any *box command, (e.g. even when
invoking 'plainbox --version')
