Avoid conflicting efi_char16_t type definitions

It's not necessary to define 'efi_char16_t' as 'wchar_t' since we don't
need any wchar functions. Besides, it may conflict with efivar-38. This
commit defines 'efi_char16_t' as 'uint16_t' and adds the conditional
check to avoid the potential conflict.

Fixes: #66
