[Buildroot] [PATCH 1/2] support/testing: remove TestZfsUclibc

[Romain Naour]

As reported on the mailing list [1] while investigating the
TestZfsUclibc Gitlab-CI failure, the python 3.13 interpreter itsef
segfault at runtime:

  Fatal Python error: _PyThreadState_Attach: non-NULL old thread state
  Python runtime state: preinitialized
  Thread 0xSegmentation fault

This issue is related to the python 3.13 version bump [2] were several
internal changes were added [3] to support PEP 703 [4].
PEP 793 is about CPython’s global interpreter lock (“GIL”) removal
for multi-threads support that requires a working C11 "thread_local"
for thread-local storage [5].

Remove TestZfsUclibc since this issue is not related to ZFS and since
we are going to disable python3 package for aarch64 uClibc-ng
toolchains.

Keeping TestZfsUclibc is possible by using another architecture than
aarch64. But it requires to update TestZfsBase.
