[PATCH 1/1] ci: split the `linux-gcc` job into two jobs

["Johannes Schindelin via GitGitGadget" <gitgitgadget@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

This job was abused to not only run the test suite in a regular way but
also with all kinds of `GIT_TEST_*` options set to non-default values.

Let's split this into two, with the `linux-gcc` job running the default
test suite, and the newly-introduced `linux-gcc-extra` job running the
test suite in the "special" ways.

Technically, we would have to build Git only once, but it would not be
obvious how to teach Travis to transport build artifacts, so we keep it
simple and just build Git in both jobs.
