compile_SUITE: Replace confusing files/2 with get_files/3

The files/2 function is confusing. The second argument names
the output directory, not the name of the source module. It is
common trap to attempt to point a different source file using
files/2.

Introduce the new get_files/3 which explicitly names the module
name.
