Rather than using a file for stuff like this, change them to be
functions in templates. Now if any template want to use them, it
can specify for example a {pre,post}_<stage>() shell function.
Also remove some NetBSD specific stuff that is not useful anymore.

If exists a patch called $pkgname-fix-{build,install}.diff in the
templates directory, they will be applied automatically. If patches
are named differently $patch_files must be used yet.
