Failed cpuidle-latency test due to kernel-devel dependency on Debian-based OS (Ubuntu 24.04)

[kumarmuthu]

Issue:

Issue line: https://github.com/avocado-framework-tests/avocado-misc-tests/blob/master/cpu/cpuidle-latency.py#L56

Problem:

On Debian-based distributions like Ubuntu 24.04, the test fails due to the kernel-devel dependency which is not available via apt.

Fix:

Replaced kernel-devel with Ubuntu equivalent linux-headers-$(uname -r) and added required linux-tools-* packages for perf functionality.

sm = SoftwareManager()
distro_name = distro.detect().name
deps = ['gcc', 'make']
if 'Ubuntu' in distro_name:
    deps.extend([
        'linux-headers-%s' % platform.uname()[2],
        'linux-tools-common',
        'linux-tools-%s' % platform.uname()[2]
    ])
elif distro_name in ['rhel', 'SuSE', 'fedora', 'centos']:
    deps.extend(['perf', 'kernel-devel'])
else:
    self.cancel("Install the package for perf supported by %s" % distro_name)

Summary:

Fix ensures cross-distro compatibility by using distro-specific packages. Now the test runs successfully on Ubuntu 24.04 as well as RPM-based distributions.
