Public bug reported:
[Impact]
The autopkgtest for bpfcc-tools fails with the following error when
multiple linux-tools packages (multiple kernels) are installed:
942s /usr/lib/linux-tools-6.8.0-22/bpftool
/usr/lib/linux-tools-6.8.0-25/bpftool gen skeleton

942s make[1]: Leaving directory '/tmp/autopkgtest.2W4dxr/build.Uhs/src'
The reason is that in debian/rules we evaluate BPFTOOL assuming that
only one kernel is installed, but we may have multiple kernels
(therefore multiple linux-tools-<version>) installed.
[Test case]
Install multiple linux-tools-<version> and run the bpfcc-tools
autopkgtest.
[Fix]
Evaluate BPFTOOL in debian/rules only taking the last bpftool listed in
/usr/lib/linux-tools-*/bpftool.
[Regression potential]
This change affects only the autopkgtest and it allows to run the test
correctly also when multiple kernels are installed, no regresssion is
expected.
