archiso_pxe_common: remove resolv.conf before copy

Booting via PXE we want to keep our DNS configuration. So remove
/etc/resolv.conf in new root before copying the current file.

Without this systemd-resolved fallback nameservers are used and we see an
error message when the root ships a symbolic link to systemd-resolved's
stub-resolv.conf:

cp: not writing through dangling symlink '/new_root/etc/resolv.conf'
