[klibc] access()

[Jon Smirl]

The access() function is there but the defines it needs are missing.

       mode is a mask consisting of one or more of R_OK, W_OK, X_OK and  F_OK.
 
       R_OK,  W_OK  and  X_OK request checking whether the file exists and has
       read, write and execute permissions, respectively.  F_OK just  requests
       checking for the existence of the file.
