extend/ENV/super: set M4 for libtool
[g]libtoolize looks for m4 using the environment variable M4. When
that isn't set, it looks for m4 in PATH.

However, when libtool is a build dependency but m4 is not, m4 will
not be found in PATH. Since it is currently not set in the
environment by superenv, this causes some builds to fail.

Closes https://github.com/Homebrew/homebrew-core/pull/73932.
