Revert "libtraceevent: Increase libtraceevent logging when verbose"

This reverts commit 08efcb4a63.

This breaks the build as it will prefer using libbpf-devel header files,
even when not using LIBBPF_DYNAMIC=1, breaking the build.

This was detected on OpenSuSE Tumbleweed with libtraceevent-devel 1.3.0,
as described by Jiri Slaby:

=======================================================================
It breaks build with LIBTRACEEVENT_DYNAMIC and version 1.3.0:
> util/debug.c: In function ‘perf_debug_option’:
> util/debug.c:243:17: error: implicit declaration of function
‘tep_set_loglevel’ [-Werror=implicit-function-declaration]
>   243 |                 tep_set_loglevel(TEP_LOG_INFO);
>       |                 ^~~~~~~~~~~~~~~~
> util/debug.c:243:34: error: ‘TEP_LOG_INFO’ undeclared (first use in this
function); did you mean ‘TEP_PRINT_INFO’?
>   243 |                 tep_set_loglevel(TEP_LOG_INFO);

>       |                                  TEP_PRINT_INFO
> util/debug.c:243:34: note: each undeclared identifier is reported only once
for each function it appears in
> util/debug.c:245:34: error: ‘TEP_LOG_DEBUG’ undeclared (first use in this
function)
>   245 |                 tep_set_loglevel(TEP_LOG_DEBUG);
>       |                                  ^~~~~~~~~~~~~
> util/debug.c:247:34: error: ‘TEP_LOG_ALL’ undeclared (first use in this
function)
>   247 |                 tep_set_loglevel(TEP_LOG_ALL);
>       |                                  ^~~~~~~~~~~

It is because the gcc's command line looks like:
gcc
...
-I/home/abuild/rpmbuild/BUILD/tools/lib/
...
-DLIBTRACEEVENT_VERSION=65790
...
=======================================================================

The proper way to fix this is more involved and so not suitable for this
late in the 5.16-rc stage.
