Build warning with meson and dtrace on Fedora 43

When I build with meson/ninja with pretty much everything enabled
and dtrace, I get the following warning:

[40/2412] Generating src/include/utils/probes.h.tmp with a custom command
Warning: /usr/bin/dtrace:.dtrace-temp.cf7b554c.d:68: syntax error near:
probe smgr__md__read__start

Warning: Proceeding as if --no-pyparsing was given.

I don't get the warning when I build with configure/make.

"git bisect" identifies the following commit as culprit:

ca326e903d "Clean up read() return type" by Peter E.

I don't know enough about dtrace to track this down, but I think it
should be fixed.

The involved software (all standard Fedora 43):

- dtrace version 5.5
- meson 1.8.5
- ninja 1.13.1
