hyprcursor_test2 and hyprcursor_test_c tests segfault in Alpine Linux

[earboxer]

Haven't quite figured this out for a while (getting these tests working is my blocking issue for moving Hyprland to community from testing), just thought I'd put this here because someone else might have some input.

(related to free-ing the raw shape data?)

(It seems like these tests work under arch, so this may be musl libc related, possible we're triggering undefined behavior of free?)
