This commit updates the custom command to build the default.metallib file to use the correct path to ../ggml-common.h by using the variable METALLIB_COMMON.

The motivation for this change is that currently when building and specifying GGML_METAL_EMBED_LIBRARY=OFF the following error is generated:

[ 11%] Linking CXX shared library ../../bin/libggml.dylib
[ 11%] Built target ggml
make[2]: *** No rule to make target `ggml/src/ggml-metal/ggml-common.h', needed by `bin/default.metallib'.  Stop.
make[1]: *** [ggml/src/ggml-metal/CMakeFiles/ggml-metal-lib.dir/all] Error 2

With the above change the build could progress but there was a follow on error about not being able to find the ggml-common.h file in ggml-metal.metal where is was included as a relative path:

[ 11%] Compiling Metal kernels
/Users/danbev/work/llama.cpp/build/bin/ggml-metal.metal:6:10: error: '../ggml-common.h' file not found, did you mean 'ggml-common.h'?
         ^~~~~~~~~~~~~~~~~~
         "ggml-common.h"
1 error generated.

Removing the relative path then allowed the build to complete successfully.

This commit updates the custom command to build the default.metallib
file to use the correct path to ../ggml-common.h by using the variable
METALLIB_COMMON.

specifying GGML_METAL_EMBED_LIBRARY=OFF the following error is
generated:
