[PATCH v2 1/3] kbuild: deb-pkg: remove support for EMAIL environment variable

[Masahiro Yamada <masahiroy@kernel.org>]

Commit edec611db047 ("kbuild, deb-pkg: improve maintainer
identification") added the EMAIL and NAME environment variables.

Commit d5940c60e057 ("kbuild: deb-pkg improve maintainer address
generation") removed support for NAME, but kept support for EMAIL.

The EMAIL and NAME environment variables are still supported by some
tools (see 'man debchange'), but not by all.

We should support both of them, or neither of them. We should not stop
halfway.
