foot: cache stimuliFile more aggressively

Browse Source 
stimuliFile would get rebuild with every change in version, since the
stimulusGenerator derivation would depend on the version string. Since
the script often doesn't change between releases, this causes
unnecessary rebuilds and cache duplication.

Additionally we add a test to passthru which checks if the hash of the
script is still up to date: By making its name depend on the version
string, it'll get rebuild on every version change, even if the hash
stays the same. This way we can detect new hash mismatches.
