Ævar Arnfjörð Bjarmason b202e51b15 grep: fix a "path_list" memory leak
Free the "path_list" used in builtin/grep.c, it was declared as
STRING_LIST_INIT_NODUP, let's change it to a STRING_LIST_INIT_DUP
since an early user in cmd_grep() appends a string passed via
parse-options.c to it, which needs to be duplicated.

Let's then convert the remaining callers to use
string_list_append_nodup() instead, allowing us to free the list.

This makes all the tests in t7811-grep-open.sh pass, 6/10 would fail
before this change. The only remaining failure would have been due to
a stray "git checkout" (which still leaks memory). In this case we can
use a "git reset --hard" instead, so let's do that, and move the
test_when_finished() above the code that would modify the relevant
file.
