I okay with the general idea, but I held off on pushing this to propose
that instead you add a notmuch-extract-patch-executable defcustom
consistent with other spots in piem (piem-git-executable,
piem-b4-b4-executable, piem-lei-lei-executable).

That can be set to "notmuch-extract-patch" by default then ...

... instead of worrying about the executable-find call here, just pass
notmuch-extract-patch-executable to call-process as is.  If call-process
can't find it, it will signal a clear enough error:
