sim: revert 6709bbcf564d

The identifier SYS_getdents is not available on Mac OS X.  Therefore, its use
results in compilation failure.  It seems there is no straight forward way to
implement the system call getdents using readdir() or similar C functions.
Hence the commit 6709bbcf564d is being rolled back.
