Fixes #72 - Replace sidekiq-selinux wrapper with direct sidekiq call

The sidekiq-selinux wrapper script exists only for SELinux domain
transition on bare-metal RPM installations. In containers, SELinux
is disabled (label=disable) so the wrapper adds no value.

Replace the wrapper call with a direct sidekiq invocation and use
an absolute path for the dynflow-sidekiq.rb script instead of a
relative one for clarity.
