sh: fix sys_cacheflush error checking
sys_cacheflush should return with EINVAL if the cache parameter is not
one of ICACHE, DCACHE or BCACHE.
So, we need to include 0 in the first check.
It also adds the three definitions above as wrapper of the existent macros.
PS: ltp cacheflush01 test now passes.
