chainlint.sed: tolerate harmless ";" at end of last line in block

chainlint.sed flags ";" when used as a command terminator since it
breaks the &&-chain, thus can allow failures to go undetected. However,
when a command terminated by ";" is the last command in the body of a
compound statement, such as `command-2` in:

    if test $# -gt 1
    then
        command-1 &&
        command-2;
    fi

then the ";" is harmless and the exit code from `command-2` is passed
through untouched and becomes the exit code of the compound statement,
as if the ";" was not present. Therefore, tolerate a trailing ";" in
this position rather than complaining about broken &&-chain.
