spicy/zeekygen: Remove mtime from generated code

Browse source 
Zeekygen implements its own make-style update logic to prevent
re-creation of files that have not changed. To fulfill this, we
currently encode the current time into spicyz generated .cc files.

This degrades ccache efficiency for built-in analyzers and also
for all .evt files compiled during testing. Switch SpicyModuleInfo
to return current time instead. This results in the re-generation
of documentation files unconditionally when running Zeekygen, but
that seems more acceptable IMO.

Generally wonder if Zeekygen should produce output unconditionally
and if we need to clobber prevention, compare with the content of
the existing file.

Closes #3619
