msvcp90/tests: Don't redefine __thiscall (try 2).

[Nicolas Le Cam]

Try 2: Just undefine __thiscall before using our own definition.

Fixes warnings on mingw-w64:
../../../../../src/dlls/msvcp90/tests/misc.c:64:0: warning:
"__thiscall" redefined [enabled by default]
<built-in>:0:0: note: this is the location of the previous definition
../../../../../src/dlls/msvcp90/tests/string.c:56:0: warning:
"__thiscall" redefined [enabled by default]
<built-in>:0:0: note: this is the location of the previous definition
