 testsuite: Simplify kernel32 glue logic

 On Windows the testsuite driver calls kernel32 to set the current
 terminal codepage. The previous implementation of this was significantly
 more complex than necessary, and was wrong in the case of MSYS2, which
 requires that we explicitly load the library using the name of its
 DLL, including its file extension.

 Test Plan: Validate on Windows
