It is because presently rpm_execcon() performs the exec call. If the
exec call is handled by the caller, then we only need the executable
path. Likewise with envp; we do not need it if the caller performs the
exec. We would just move the remaining logic to set up the exec context
from libselinux rpm_execcon() into the rpm selinux plugin code; as rpm
is the only user of it, there is no real reason for it to live in
libselinux vs being part of an rpm plugin.
