[PATCH] oeqa/selftest: clear SANITY_TESTED_DISTROS instead of failing

[Babanpreet Singh <bbnpreetsingh@gmail.com>]

oe-selftest refuses to run when SANITY_TESTED_DISTROS is set, and
poky.conf sets it:

  Please unset SANITY_TESTED_DISTROS in order to run oe-selftest

Clear it in the test build directory with :forcevariable, so a value
set through an override goes too, and drop the check.

[YOCTO #11933]
