8181313: SA: Remove libthread_db dependency on Linux

[jerboaa]

This backport fixes tier1 test failures in the serviceability area for systems using glibc 2.33. On those system attaching to a different process doesn't work currently:

$ export LIBSAPROC_DEBUG=true
$ jhsdb clhsdb --pid 148082
Attaching to process 148082, please wait...

https://sourceware.org/bugzilla/show_bug.cgi?id=27526

The proposal is to remove the need of thread_db entirely as it's not need (which brings JDK 11) in line with JDK 17+

The patch didn't apply cleanly. Conflicts where only in copyright headers.

Testing:

• tier1 on Linux x86_64 with glibc 2.33 (fails prior, passes after patch).

Thoughts?
