Reduce the size of the installer

A comprehensive list of candidate files to remove from the installer was
obtained by running the tests with GIT_TEST_INSTALLED=/mingw64/bin/
after starting Sysinternals' Process Monitor, filtering the output by
the path of the portable Git, then saving the output as CSV and
post-processing it with

	sed -n "2,\$s/\([^,]*,\)\{4\}\"\([^\"]*\).*/\2/p" /c/Logfile.CSV |
	uniq |
	tr \\\\ / |
	sed -n "s/^C:\/minimize-portable-git\///p" |
	sort |
	uniq |
	tee /c/min.paths

then -- once -- running

	(cd / && find -xdev -type f) |
	grep -v "^\\./\(bin\|tmp\)/" |
	sed -n "s/^\\.\\///p" |
	tee /c/cur.paths

in the portable Git directory, and then determining which files have not
been used by the test suite with

	cat /c/cur.paths /c/min.paths /c/min.paths |
	sort |
	uniq -u |
	tee /c/unneeded.paths

Of course this was followed by a very careful analysis in order to avoid
overzealous culling (e.g. file(1)'s `/usr/share/misc/magic.mgc` file is
still needed, even if the test suite does not use the file tool).

To allow dropping the entire terminfo file tree *except* for the
required "dumb" and "xterm" family, we use an extra grep call using GNU
grep's `--perl-regexp` option to switch to Perl-style regular
expressions, allowing negative look-ahead to be used (we cannot just
turn the entire grep call into a single `--perl-regexp` call, though,
because that option allows only one pattern).

In this developer's tests, this patch reduced the size of the installer
from around 43MB to 27MB.

This fixes git-for-windows/git#262.
