Avoid newlines in some AT_CHECK commands.

[Ralf Wildenhues]

It bothered me while testing these test groups that TESTSUITEFLAGS='-v -x'
doesn't show the trace output for these commands.  Fixed with this
trivial patch by avoiding newlines inside, pushed.

Cheers,
Ralf

        Avoid newlines in some AT_CHECK commands.
        * tests/standalone.at (linking libltdl without autotools): Wrap
        lines with dnl, to avoid turning off tracing of AT_CHECK.
        * tests/subproject.at (linking libltdl without autotools):
        Likewise.
