Subject: [PATCH] libnm-systemd-core: Disable sd_dhcp6_client_set_duid_uuid
 function

When building on musl systems ( with out systemd ), and using LLD linker
from LLVM project we fail to link with undefined symbols.

This symbol is in sd_id128.c but its disabled, so let disable the functions
which need this function.

| x86_64-yoe-linux-musl-ld.lld: error: undefined symbol: sd_id128_get_machine_app_specific
| >>> referenced by sd-dhcp-duid.c:202 (/usr/src/debug/networkmanager/1.48.0/../NetworkManager-1.48.0/src/libnm-systemd-core/src/libsystemd-network/sd-dhcp-duid.c:202)
| >>>               libnm-systemd-core.a.p/src_libsystemd-network_sd-dhcp-duid.c.o:(sd_dhcp_duid_set_uuid) in archive src/libnm-systemd-core/libnm-systemd-core.a
| x86_64-yoe-linux-musl-clang: error: linker command failed with exit code 1 (use -v to see invocation)
