FYI: testsuite: drop some unused variables and functions

[Ralf Wildenhues]

Applied this.  The only nontriviality was the last hunk, which is
leftover after I moved that bit of test to be done in mdemo-exec,
quite a while ago.

Cheers,
Ralf

        * tests/am-subdir.at: Drop unused variables.
        * tests/configure-iface.at: Likewise.
        * tests/ctor.at: Likewise.
        * tests/early-libtool.at: Likewise.
        * tests/lt_dladvise.at: Likewise.
        * tests/old-m4-iface.at: Likewise.
        * tests/lt_dlexit.at: Likewise.  Also drop unused functions.
