run-posix-option-group-test: replace CWD qith PWD

When running LTP on a mininal Busybox + uClibc env, see lot of prints like this:

| Usage: basename FILE [SUFFIX]
|
| Strip directory path and .SUFFIX from FILE
|
| *******************
| Testing
| *******************

This is because $CDW env variable is not provided by Busybox shell.

I understand PWD is not same as CWD, but should suffice here !

Hi!

Actually this looks like a typo to me. Since there is no $CWD in bash either (there is one in csh though).

I'm getting this with bash:

basename: missing operand
Try 'basename --help' for more information.

So I've pushed the patch with a bit different changelog.
