BUG/MINOR: tcpcheck: report correct error in tcp-check rule parser

When parsing tcp-check expect-header, a copy-paste error in the error
message causes the name of the header to be reporetd as the invalid
format string instead of its value. This is really harmless but should
be backported to all versions to help users understand the cause of the
problem when this happens. This was reported in GH issue #2586 by
@Bbulatov.
