dos/meson: add a hint for setting sys_root
I found that cross-compiling with GCC 12.2.0 targeting DJGPP from Linux on x86_64 that meson used my system include directory (/usr/include/x86_64-linux-gnu/) and pulled in include files that are incompatible with DJGPP. Setting sys_root prevents meson from assuming they're compatible between the build and host systems, fixing those compile-time errors.
TEST=meson setup --cross-file meson_cross/i586_djgpp_dos.txt; ninja libflashrom.h no longer causes "features.h: No such file or directory" errors via /usr/include/x86_64-linux-gnu/sys/types.h
