 Fix abort and import lib search on Windows

 Summary:
 Apparently `sysErrorBelch` doesn't terminate the program anymore making
 previously unreachable code now execute. If a dll is not found the error
 message we return needs to be a heap value.

 Secondly also allow the pattern `lib<name>` to be allowed for finding an
 import library with the name `lib<name>.dll.a`.

 Test Plan: ./validate, new tests T13082_good and T13082_fail
