pxe_dns: remove obsolete pxe_dns.c wrapper

We used to need a wrapper around the core function dns_resolv() to
implement pxe_dns(), because the former function required its argument
to live in low memory.  This is no longer the case and hasn't been for
a while, so remove this unnecessary level of indirection.
