Reload nameserver information on lookup failure
As discussed in #41570, UNIX systems often cache the contents of /etc/resolv.conf, which can cause lookup failures to persist even after a network connection becomes available. This patch modifies lookup_host to force a reload of the nameserver entries following a lookup failure. This is in line with what many C programs already do (see #41570 for details). On systems with nscd, this should not be necessary, but not all systems run nscd. Introduces an std linkage dependency on libresolv on macOS/iOS (which also makes it necessary to update run-make/tools.mk). Fixes #41570. Depends on rust-lang/libc#585.
