package/mesa3d-demos: fix build failure on musl

Patch has been on upstream main for close to 2 years.

The "uint" use was introduced with [1] and [2], released with
mesa3d-demos 9.0.0 from March 2023, and added to Buildroot with commit
80304d9911 "package/mesa3d-demos: bump version to 9.0.0". The affected
code is built only if Wayland and Vulkan support are enabled, that is:

BR2_PACKAGE_LIBDECOR=y
BR2_PACKAGE_VULKAN_LOADER=y
BR2_PACKAGE_WAYLAND=y
