scripts: pass BUILD_TARGET directly to test scripts

There is no need to reconstruct it from within the scripts since the
main script already constructed it once.

Drop the previously useless setting of BUILD_TARGET from various
scripts. The value was always overwritten at a later point.

No functional change intended.
