pango: use bsearch() implementation from Musl libc 

See https://github.com/termux/termux-packages/issues/4284.

Note: bsearch implementation in Bionic didn't changed since
Thu Feb 20 14:15:09 2014, though issue #4284 is not reproducible
on recent Android versions. Patch is applied for both branches.
