Conflicting types for efi_char16_t

When I try to compile mokutil (current master branch), it fails with the following message:

In file included from efi_hash.h:38,
                 from efi_hash.c:36:

I think it might have to do with me using musl as my libc implementation, given this bug for mokutil 0.5.0, and that I can successfully compiled it on a glibc system. In any case, the issue is that the definition is different from the definition given by efivar 38. Simply deleting the line with the conflicting definition allows me to compile mokutil without errors.

lcp / mokutil
