mail/dovecot2-pigeonhole: update to 0.5.11

Update dovecot2-pigeonhole to 0.5.11.

v0.5.11 2020-08-12  Aki Tuomi <aki.tuomi@open-xchange.com>

	* managesieve: managesieve_max_line_length setting is now a "size" type
	  instead of just number of bytes. This allows using e.g. "64k" as the
	  value.
	- lib-sieve: When folding white space is used in the Message-ID header,
	  it is not stripped away correctly before the message ID value is used,
	  causing e.g. garbled log lines at delivery.
