t9001-send-email.sh: fix quoting for mailrc --dump-aliases test

The .mailrc alias file format documents that multiple addresses are
separated by spaces. The alias file used in the t9001 --dump-aliases
mailrc test have addresses which include both a name and email. These
are unquoted, so git send-email will parse this as an alias that
translates to multiple independent addresses.

The existing test does not care about this, as --dump-aliases only dumps
the alias and not the address. However, it is incorrect for a future
where --dump-aliases could also dump the mail addresses.

Fix the test to quote the aliases properly, so that they translate to a
single address.
