kernel32/tests: Fix actctx tests on Vista+

[Ge van Geldorp]

Vista and higher seem to cache the presence/absence of external .manifest
files. When starting "kernel32_test.exe actctx" Windows appears to record
that no kernel32_test.exe.manifest file is present. As part of the test,
we create that manifest file and launch "kernel32_test.exe actctx
manifest1" to do some tests with an external .manifest file. However,
Windows simply doesn't seem to load the .manifest in the child process.

If I start from a clean snapshot, manually create the .manifest file and
then run the child test ("kernel32_test.exe actctx manifest1") the child
test runs fine. After removing the .manifest file and running the parent
test ("kernel32_test.exe actctx") the child will still load the .manifest
correctly.

Changing the last modified date of the executable appears to prevent the
cache from being used.
