service-ids-check: Add check uid/gid of servicesflounder_5.99.1flounder/5.99.15.99.1
This new test allows to check whether service run with expected uid and gid. This check doesn't check that the service runs because there is an other check for that. It currently only checks weston service to run as display/display but it can be easily extended for checking other services. Bug-AGL: SPEC-546 Signed-off-by: jobol <jose.bollo@iot.bzh>

+# This scripts allows to check the ids (user and/or group)
+# of running services.
+# It doesn't check that the service runs because this is
+# the object of other tests.
+# If a process doesn't run it emits an unknown status for
+# the service, but not a fail.
+# When there are multiple instance of a service, it checks
+# that at least one instance matches expectation.
