[release-branch.go1.14] cmd/go: fix parallel chatty tests on solaris-amd64 builder

The parallel chatty tests added in CL 229085 fail on the
solaris-amd64-oraclerel builder, because a +NN:NN offset time zone is
used. Allow for the `+` character in the corresponding regex to fix
these tests. Also move the '-' to the end of the character class, so it
is not interpreted as the range 9-T.

Updates #38458.
For #39308.
