Shell portability issue in tests/key-id/key-id

[Tom G. Christensen-2]

The tests/key-id/key-id script uses 'if !' which is not understood by
/bin/sh and results in an error on IRIX and Solaris.

$ ./key-id
!: Not found

-tgc

Alas it is not portable, see:

I have rewritten the code, thanks for the report Tom.
