[scudo][standalone] Fix tests makefile

Summary:
A missing `STATIC` entailed some annoying to debug failures wrt 32 vs 64
binaries. Additionally I noticed I was using the wrong variable (the Scudo
one as opposed to the Scudo Standalone one).

See https://reviews.llvm.org/D58184#1412417 and below for discussion.
