[OE-core][PATCH v2] psmisc: add ptest support

[Pratik Farkase <pratik.farkase@est.tech>]

Add ptest support using psmisc's upstream DejaGnu testsuite, which
exercises killall, pslog and fuser via their .exp scripts. The tools and
the testsuite helper programs (socket_test, test-listen) are installed
under a src/ layout so the scripts' ${topdir}src/<tool> paths resolve on
target.

Notes:
    Changes in v2:
    - Point mktemp at a private, symlink-resolved TMPDIR in run-ptest so the
      fuser -a/-av/-va tests do not fail intermittently on the autobuilder
      when /tmp is a symlink or on a different mount.
