t9001: use older Getopt::Long boolean prefix '--no' rather than '--no-'

The '--no-chain-reply-to' option is a Getopt::Long boolean option. The
'--no-' prefix (as in --no-chain-reply-to) for boolean options is not
supported in Getopt::Long version 2.32 which was released with Perl 5.8.0.
This version only supports '--no' as in '--nochain-reply-to'.  More recent
versions of Getopt::Long, such as version 2.34, support either prefix. So
use the older form in the tests.
