t4210: skip more command-line encoding tests on MinGW

In 5212f91 ("t4210: skip command-line encoding tests on mingw",
2014-07-17) the positive tests in this file were skipped. That left
the negative tests that don't produce a match.

An upcoming change to migrate the "fixed" backend of grep to PCRE v2
will cause these "log" commands to produce an error instead on
MinGW. This is because the command-line on that platform implicitly
has its encoding changed before being passed to git. See [1].
