FYI: make new tests a bit more autotest-friendly

[Ralf Wildenhues]

Applied to HEAD: Autotest disables tracing for the braced type of
parameter expansion but not for the unbraced (and has good reason
to do so).  Since traces are helpful, let's not use them if they
are not necessary.  This only matters for AT_CHECK, but to be
consistent, I changed the other usages as well.

Cheers,
Ralf

        * tests/inherited_flags.at: Drop `${parameter}' for `$parameter'
        where appropriate, for improved `testsuite -x' output.
