[PATCH] ld: testsuite: Fix a few backslash-related issues on MinGW.

Several relatively new test cases fail on MinGW:
[...]
Running /d/Works/binutils/ld/testsuite/ld-archive/archive.exp ...
FAIL: Script fake archive link
FAIL: Script fake whole archive link
FAIL: Script fake group archive link accept
[...]

This is because on Windows ld uses "\" instead of "/" to create full file
names as shown in the log below:
