Disable nscd and enable systemd-resolved by default (#426)

Changes:
- Disable nscd support in glibc
- Disable crypt support in glibc and move it to libxcrypt
- Enable systemd-resolved by default
- Update nss-mdns to v0.15.1
- Clean up the network-manager package a bit, notably:
  - Switch to meson build
  - Use internal dhcp implementation instead of dhclient (EOL upstream)
  - Fix how it's enabled by default
- Remove dnsmasq as rundep (superseded by systemd-resolved
functionality)
  - Cleanup 32bit package
- Remove unneeded dhclient (superseded by network-manager internal dhcp
client) and libnm-legacy (only used by Scout/Heavy steam runtimes,
doesn't build anyway and not easy to fix)

Closes #422
