Previously we patched sys/wait.h to add it, but patch was removed in
commit 3879280345 ("ndk-patches: remove wait3 patch from
sys/wait.h") since busybox (for which the patch was added) no longer
needs it.
Let's patch the packages that actually needs this instead of
ndk-headers, to keep track of which packages that need it.
Fixes https://github.com/termux/termux-packages/issues/9257.
