dtrace issue on releng/13.0

[Dean E. Weimer]

I just built and installed FreeBSD 13.0 Beta 3 from source checked out 
with last commit of 4b737a9c58cac69008f189cc44e7d1a81a0b601c after the 
install I was installing a few ports, and perl5.32 failed to build 
stating dtrace -h not available.

root at fbsd13-devel:/ # dtrace -h
dtrace: failed to establish error handler: "/usr/lib/dtrace/psinfo.d", 
line 1: failed to copy type of 'pr_uid': Type information is in parent 
and unavailable

The initial install from the FreeBSD-BETA3 iso image does work as 
expected, so the problem was introduced since then.

root at fbsd13:/jails/devel # dtrace -h
dtrace: -h requires one or more scripts or enabling options

It does appear that the commit 	ae093a0614f30d4cdffb853e4eba93322e8ed8f4 
references changes to dtrace.
