As with previous commits, we’re enabling `-Wsign-conversion` piecemeal
for all of glib.git.
It turns out that gthread didn’t have any `-Wsign-conversion` warnings
at all, so this was straightforward.

Helps: #3405
Meson supports tap protocol results parsing, allowing us to track better
the tests that are running (and the ones that are actually skipped) without
manually parsing the test output.
However this also implies that using the verbose mode for a test doesn't
show its output by default (unless there are failures).
It’s deprecated, but the big red 0/0/0 line for the `glib/gthread`
directory in the lcov output for GLib is driving me nuts.
