Bug #20910: leaked-globals not happy about dtrace related symbols
https://bugs.ruby-lang.org/issues/20910

* Author: Kulikjak (Jakub Kulik)
* Status: Open
* ruby -v: ruby 3.3.6 (2024-11-05 revision 75015d4c1f) [amd64-solaris2.11]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
I am not sure if this is Solaris specific, but when I build Ruby 3.3.6 with dtrace enabled and run its test suite, the leaked-globals checker fails with the following:
```
Checking leaked global symbols...48 un-prefixed symbols leaked
leaked
  __dtraceenabled_ruby___array-create
  __dtrace_ruby___array-create
  __dtraceenabled_ruby___raise
  __dtrace_ruby___raise
  __dtraceenabled_ruby___gc-sweep-begin
....
```

I believe that these are not problematic and can be there.

The following simple change fixed the issue:
```diff
