use 'jot' if available (was: automake-1.11 test failure on darwin9 - instmany-python.test)

Hi Peter,

thanks for the bug report; will address in a separate message.  For now:

That sounds like a good idea to me.  I didn't know jot.
I'm pushing this.

Cheers,
Ralf

    testsuite: also try `jot' as `seq' replacement.
    
    * tests/instmany-mans.test: Try BSD `jot' before resorting to a
    slow but portable shell loop.
    * tests/instmany-python.test: Likewise.
    * tests/instmany.test: Likewise.
    Suggestion by Peter O'Gorman.
