cbmem: Fix makefile

The .dependencies rule did not use the CPPFLAGS variable which led
    to funny behavior: a spurious termination message the first time
    (after checkout/make distclean) one executes make. Afterwards the
    (wrongly) empty .dependencies file hides the problem and the binary
    is created anyway.

$ make
    cbmem.c:37:34: fatal error: boot/coreboot_tables.h: No such file or directory
    compilation terminated.
    cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86  -c -o cbmem.o cbmem.c
    cc   cbmem.o   -o cbmem

$ make
    make: Nothing to be done for `all'.

$ make clean
    rm -f cbmem *.o *~

$ make
    cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86  -c -o cbmem.o cbmem.c
    cc   cbmem.o   -o cbmem

$ make distclean
    rm -f cbmem *.o *~
    rm -f .dependencies

$ make
    cbmem.c:37:34: fatal error: boot/coreboot_tables.h: No such file or directory
    compilation terminated.
    cc -O2 -Wall -Werror -iquote ../../src/include -iquote ../../src/src/arch/x86  -c -o cbmem.o cbmem.c
    cc   cbmem.o   -o cbmem

I fixed that by adding the CPPFLAGS variable to the .dependencies recipe, just
    like Stefan Reinauer did in Chromium (Ia9d2e10a3ef122f30d681d16c2291eb108ead835),
    hence the split sign-off for this tiny change. :)
