bitbake: bitbake: Add --skip-setscene option

Adds an option to skip _setscene only if they would normally be
executed, without ignoring sstate completely.

Previously, '--no-setscene' would allow a build that completely ignored
sstate and _setscene tasks, and '--setscene-only' would allow a build
that only ran _setscene tasks, but there was no option do a build that
would respect tasks previously restored from sstate and build everything
else. Now one can run:

 bitbake --setscene-only IMAGE; bitbake --skip-setscene IMAGE

which is functionally equivalent to:

 bitbake IMAGE

The indented use is to allow a build to complete successfully in the
presence of _setscene task failures by splitting apart the two phases
e.g.:

 (bitbake -k --setscene-only IMAGE || true) && bitbake --skip-setscene IMAGE

(Bitbake rev: 813ba5b7c13b573a0b813b628a819bdbf0627540)
