nfs-utils: make makesock() static

Clean up:  The makesock() function can become static since it is only used in
rpcmisc.c, where it is defined.  Fix some minor nits while we're in the area:

 o  Move it so we can remove it's forward declaration.

 o  Get rid of unneeded newlines in the xlog() format strings.

 o  Use htonl(INADDR_ANY) instead of INADDR_ANY to initialize sin_addr.
    Should make no run-time difference, but is slightly more proper,
    as the standard definition of INADDR_ANY is in host byte-order.

 o  Remove the parentheses in the "return" statements.
