[PATCH 07/10] classes/populate_sdk_ext: properly determine buildtools filename

[Paul Eggleton <paul.eggleton@linux.intel.com>]

Determine the name of the current buildtools installer ahead of time,
set it in a variable and use that variable rather than the wildcarded
version everywhere, since it's much tidier.
