linuxptp: fix cross compilation not using host headers

Previously my morty build failed as follows:

| arm-angstrom-linux-gnueabi-gcc  -march=armv7-a -mthumb -mfpu=neon  -mfloat-abi

| <builtin>: recipe for target 'msg.o' failed
| make: *** [msg.o] Error 1

As it tried using the kernel headers from my Fedora 23 build server
located at /lib/modules/4.8.13/build/usr/include.

Fix this by no longer calling the incdefs.sh shell script from the
makefile.
