[PATCH v2 01/10] t/test-lib: fix quoting of TEST_RESULTS_SAN_FILE

When assembling our LSAN_OPTIONS that configure the leak sanitizer we end up prepending the string with various different colon-separated options via calls to `prepend_var`. One of the settings we add is the path where the sanitizer should store logs, which can be an arbitrary filesystem path.

Naturally, filesystem paths may contain whitespace characters. And while it does seem as if we were quoting the value, we use escaped quotes and consequently split up the value if it does contain spaces. This leads to the following error in t0000 when having a value with whitespaces:

    .../t/test-lib.sh: eval: line 64: unexpected EOF while looking for matching `"'
    ++ return 1
    error: last command exited with $?=1
    not ok 5 - subtest: 3 passing tests

The error itself is a bit puzzling at first. The basic problem is that the code sees the leading escaped quote during eval, but because we truncate everything after the space character it doesn't see the trailing escaped quote and thus fails to parse the string.

Properly quote the value to fix the issue while using single-quotes to quote the inner value passed to eval. The issue can be reproduced by t0000 with such a path that contains spaces.
