Valgrind setup fails on Ubuntu/Debian derivative distributions (e.g. Pop!_OS)

Lines 24 to 35 in a7eb6e2

Running cargo test on Ubuntu-derivative distros (e.g. Pop!_OS for me) causes 14 valgrind executor tests to fail with: Unsupported system.

Since Pop!_OS is a derivative of ubuntu|debian, I though we could adapt the process to accept other distros that are close to Ubuntu and Debian

Root cause

sysinfo::System::distribution_id() returns the distro's own ID (e.g. "pop" for Pop!_OS), not its parent. LinuxDistribution::from_id() only exact-matches "ubuntu" and "debian", so derivatives fall through to Other. Which get_codspeed_valgrind_filename() doesn't handle.

Proposal

Use System::distribution_id_like() (available since sysinfo@0.35 I think) as a fallback: if the primary ID is unrecognized, walk the parent chain (["ubuntu", "debian"]` for Pop!_OS) until a known distro is found.

https://docs.rs/sysinfo/0.38.4/sysinfo/struct.System.html#method.distribution_id_like

This requires bumping sysinfo from 0.33.1 to 0.38.4, which also involves adapting one call site where physical_core_count() became an associated function.

Affected systems

Any Linux distro where ID != ubuntu|debian but ID_LIKE contains one of them.
