esp8266/modnetwork.c: Expose configuration for station DHCP hostname.

The ESP SDK supports configuring the hostname that is
reported when doing a DHCP request in station mode.  This commit
exposes that under network.WLAN(network.STA_IF).config('dhcp_hostname')
as a read/write value similar to other parameters.
