Sometimes valgrind doesn’t count the calloc() call at the innermost
stack frame, and counts it as g_type_create_instance() instead.

These were spotted by running the entire test suite under valgrind,
thanks to the magic of Meson: see the build rules in valgrind-x86_64 in
.gitlab-ci.yml.

Valgrind will check that the third argument to ioctl() is a valid
pointer, but some ioctls interpret that argument as an integer, and that
is the case here (it's a file descriptor), so this is a false positive.

While we cannot get Valgrind to automatically load this suppression file
for applications which link to GLib
(https://bugs.kde.org/show_bug.cgi?id=160905), we can at least install
it on systems in a shared directory, so that developers can use a
standardised (and up-to-date) suppressions file for GLib, rather than
rolling their own.
The file will typically be installed to:
/usr/share/glib-2.0/valgrind/glib.supp
Distributors: it is recommended that this suppression file be installed
as part of the development package for GLib in your distribution.
