50cd.ztst fails if run from unresolved path

[Adam Spiers <adam@xxxxxxxxxx>]

I just tried `make test' on the latest CVS tree, in a directory
/opt/zsh, which is a symlink to /mnt/hda7/opt/zsh.  50cd.ztst failed,
because the test assumes that $mydir is absolute:

cd Test ; make check
make[1]: Entering directory `/mnt/hda7/opt/zsh/Test'
for f in *.ztst; do \
  ../Src/zsh ztst.zsh $f; \
done
01grammar.ztst: all tests successful.
02alias.ztst: all tests successful.
03quoting.ztst: all tests successful.
