httpd: permit non-default home directory with NOMMU enabled

When BusyBox is compiled with NOMMU enabled running httpd with
the '-h' option fails even if the specified directory exists:

   $ ls -d www
   www
   $ busybox httpd  -fvvvp 8080 -h www
   ...
   ... try to access http://localhost:8080/www
   ...
   httpd: can't change directory to 'www': No such file or directory

The parent process executes xchdir("www").  When a connection is accepted
it's handled by re-executing httpd in inetd mode.  The child process
inherits the current directory "www" and tries to change directory again
to "www", which fails.

Omit the call to xchdir() when httpd is re-executed.
