mescc: Mes C Library: Add M2-Planet support.

Mes can now be built with M2-Planet by running

    kaem --verbose --strict

* include/linux/x86/syscall.h (SYS_getcwd, SYS_dup, SYS_dup2,
SYS_unlilnk, SYS_gettimeofday, SYS_clock_gettime, SYS_time): Move to
libc section.  Add M2-Planet constants.
* include/m2/lib.h (struct timezone, struct timespec): struct timeval):
Define.  Add M2-Planet flavor prototypes for mes libc.
* include/mes/m2.h: Remove macros.
* include/mes/mes.h (g_start_time, __gettimeofday_time,
__get_internal_run_time_ts): Declare.
* src/mes.c (init): Initialize them.
* src/posix.c: Use them.
* simple.make: Use them.  Remove macro preprocessing for M2-Planet.
* kaem.run: New file.
