Fixed processing of SERVER_NAME after 77aad2c142a0.

Previously, the nxt_router_prepare_msg() function expected server host among
other headers unmodified.  It's not true anymore since normalization of the
Host header has been introduced in 77aad2c142a0.

The nxt_unit_split_host() function was removed.  It didn't work correctly with
IPv6 literals.  Anyway, after 77aad2c142a0 the port splitting is done in router
while Host header processing.
