Philip Withnall 087272777b tests: Fix incorrect basename comparison in gsubprocess test 
This was causing intermittent failures on macOS, depending on whether
the tmpdir ended with a `/` or `/some-dir`. `g_strrstr()` is not the
right function to use to extract a basename from a path, for this
reason.

When it failed, the macOS test was failing with:
```
ok 16 /gsubprocess/env
Bail out! GLib-GIO:ERROR:../gio/tests/gsubprocess.c:1507:test_cwd: assertion failed (basename == tmp_lineend_basename): ("/T\n" == "/\n")
```

The test now passes reliably, which means that it can be removed from
the list of expected failures on macOS.

* to avoid fd conflation issues, e.g. it should properly handle 5 -> 4 and
* 4 -> 5 at the same time. GIO previously attempted to handle this by naively
* dup'ing the source fds, but this was not good enough because it was
* possible that the dup'ed result could still conflict with one of the target
* fds. For example:
*
* source_fd 5 -> target_fd 9, source_fd 3 -> target_fd 7
*
* dup(5) -> dup returns 8
* dup(3) -> dup returns 9
*
* After dup'ing, we wind up with: 8 -> 9, 9 -> 7. That means that after we
* dup2(8, 9), we have clobbered fd 9 before we dup2(9, 7). The end result is
* we have remapped 5 -> 9 as expected, but then remapped 5 -> 7 instead of
* 3 -> 7 as the application intended.
*
* This issue has been fixed in the simplest way possible, by passing a
* minimum fd value when using F_DUPFD_CLOEXEC that is higher than any of the
* target fds, to guarantee all source fds are different than all target fds,
* eliminating any possibility of conflation.
*
* Anyway, that is why we have the unused_pipefds here. We need to open fds in
* a certain order in order to trick older GSubprocess into conflating the
* fds. The primary goal of this test is to ensure this particular conflation
* issue is not reintroduced. See glib#2503.
*
* This test also has an alternate mode of operation where it instead tests
* for conflation with gspawn's child_err_report_fd, glib#2506.
*
* Be aware this test is necessarily extremely fragile. To reproduce these
* bugs, it relies on internals of gspawn and gmain that will likely change
* in the future, eventually causing this test to no longer test the bugs
* it was originally designed to test. That is OK! If the test fails, at
* least you know *something* is wrong.
