[LTP] [PATCH] cmdlib: Update exists function to exit with TCONF

[Kory Maincent]

The exists function which tests the existence of a command was returning
an error.
Update it to return TCONF and exit with the value 32.

This function is only used by ftp01.sh test.
The real effort should be to rewrite ftp01 test to the new API, but I did
not manage to do it properly and makes it compatible with the other
ftp clients.
