selftest: Avoid sstate corruption by calling cleansstate

Currently selftest doesn't use sstates because some tests
clean sstate cache; using sstates would give a performance
boost instead of building everything from scratch.

With this sstates are not corrupted using different methods
depending on tests:

devtool: These tests needed to delete the cache so SSTATE_DIR
as SSTATE_MIRRORS and set a temporal SSTATE_DIR.

sstatetests: This module already used a temporal SSTATE_DIR, so
just set up the SSTATE_MIRRORS.

Rest: Removed cleansstate, some of them required to force a
certain task, others were just removed or changed for another
task.
