Major restructure of dialyzer's testsuite

Generation of the PLT is now performed without using OS commands.
We still try to copy in the default plt to make small scale testing
efficient. If generation/checking fails, suites are skipped except
plt_tests_SUITE which contains a bare PLT check that fails normally.
