systemd-boot: Fix build on musl

systemd efi.h defines wchar_t from compiler provided __WCHAR_TYPE__
therefore we do not want it to come from alltypes.h in musl case which
otherwise will end up with conflicting definitions of wchar_t, defining
__DEFINED_wchar_t ensures that alltypes.h does not provide it
