[compiler-rt] [test] Look for the right file name suffix for arm targets

Compiler-rt libraries on arm use "arm" or "armhf" as suffix, not
the full exact arch name like "armv7".

This matches what was done for the build system in
8e11bed, to match the names that
Clang expects (in getArchNameForCompilerRTLib in Clang).

This fixes building a large number of the compiler-rt tests for
Windows/armv7.
