[PATCH v2 2/2] selftests/cachestat: add cleanup for leftover tmpshmcstat file

[Madhur Kumar]

The cachestat test generates a temporary file named
"tmpshmcstat" when it runs, but this file is not removed by
'make kselftest-clean'. Add an EXTRA_CLEAN entry to ensure
the file gets cleaned up properly.

v2:
- Corrected subject line to describe "tmpshmcstat" as a file, not a binary.
- Refined commit log for clarity
