Add a second test, shortseek(), to make sure that seekdir() also works

correctly when moving the directory pointer by small distances.
This is currently failing, i will send an updated libc/gen patch
to fix this right afterwards.

Move the functions createfiles() and delfiles() to utils.{h,c} for reuse.
Minor cleanup in telldir.c.
