ptest-runner: Allow running of specific tests

By default ptest-runner executes all ptests found in a system.
With this change, ptest-runner can be given a list of ptest
package names to run (the default is still available).

For example, to run only the zlib and rt-tests ptests:
"ptest-runner zlib rt-tests"
