fix: e2e port-25 check misparsed wrapped master.cf continuation lines
Found running the new checkPort25ConfigCombinations on selfpost.mixfed.ru: it
compared against raw, unnormalized master.cf text. postconf -F "*/*/chroot=n"
(unconditional, runs after our smtp/inet edits) rewraps the whole file using
master.cf's own line-continuation convention, splitting a single -o value
across lines and re-flowing what were separate -o lines into one paragraph.
Valid Postfix syntax -- postfix check passes -- but plain substring matching
against the raw text broke on it.

parseSMTPInetOptions now joins continuation lines into one token stream and
reconstructs each "-o param=value" assignment before comparing, verified
against a real captured stanza in port25_config_check_test.go. Full make e2e
(13 scenarios plus the two new parser unit tests) is green on the server.
