oeqa/sdk: add some buildtools tests

These two tests are designed to exercise the buildtools-tarball.

SanityTests simply verifies that inside the SDK, some commands are used
from the SDK.

BuildTests creates a new OE build directory and builds virtual/libc to
verify that a basic build works correctly. DL_DIR is reused to avoid
needless downloading, but sstate is not shared to ensure a build does
happen.
