package/wpa_supplicant: Add patch to fix build error with musl

Add a patch to allow building wpa_supplicant with the musl C library.

Building wpa_supplicant with the musl C library fails since musl does not
define type names such as '__uint32_t'. To support building wpa_supplicant
with the musl C library use the integer types declared in the ISO C standard
header file <stdint.h>.

Patch is sent upstream:
