net/wmwifi: Fix runtime on amd64

Currently wmwifi doesn't start on amd64 and simply fails with

wmwifi: No wireless interface found!

The code assumes that sizeof(int) == sizeof(size_t) which isn't the
case on amd64 (and other architectures) and all sysctl() calls will
fail because of it.

While here:

• Fix a build failure when automake+autoconf are installed in the build environment. By patching configure.in the build wants to regenerate configure which doesn't work correctly:

• Error code 1
  
  Remove files/patch-configure.in and pass CFLAGS through CONFIGURE_ENV instead.

• Add LICENSE, LICENSE_FILE
• Add missing dependency on libXext
