dvb-apps: Fix generate-keynames.sh script for cross-compilation

Fix generate-keynames.sh script for cross-compilation

generate-keynames.sh reads /usr/include/linux to find the keyname

symbols. However, when cross-compiling, the include path points

somewhere else. Allow the user to pass CROSS_ROOT to point to the

root of the cross-compilation environment.
