Quit the autotools build system.

For a simple package like guile-email, the autotools build system is
more trouble than it is worth. We prefer a hand-written Makefile. As
the commit summary suggests, the autotools are indeed a bad habit that
we must "quit".

* Makefile: New file.
* Makefile.am, bootstrap.sh, configure.ac, pre-inst-env.in: Delete
files.
* build-aux/test-corpus.scm.in: Rename to ...
* build-aux/test-corpus.scm: ... this. Remove shebang.
* build-aux/test-driver.scm.in: Rename to ...
* build-aux/test-driver.scm: ... this. Remove autotools specific
parts.
* guix.scm: Import (guix utils).
(guile-email)[arguments]: Add prefix to #:make-flags. Delete configure
phase.
* .gitignore: Remove INSTALL, Makefile, Makefile.in, aclocal.m4,
autom4te.cache, build-aux/install-sh, build-aux/missing,
build-aux/test-corpus.scm, config.log, config.status, configure,
doc/.dirstamp, pre-inst-env, test-suite.log, tests/*.log and
tests/*.trs.
