LOG: [NFCI] clarify that asan-*linux.cpp files affect *nix OS'es (#195565)

**Prior Work:** Aims to supersede (#132263), which seems inactive,
specifically by applying my own comment:
https://github.com/llvm/llvm-project/pull/132263#issuecomment-3051238734

**Context:** It aims to minimally document that the
`asan_(malloc_)?linux.cpp` files may impact non-linux OS'es (despite the
name) such as Solaris, BSD, and other *nix OS'es. This is worth
documenting as otherwise we risk breakage due to confusion, as occurred
[here](https://github.com/llvm/llvm-project/pull/131975#issuecomment-2741097471).

This is done simply by minimally augmenting the file header comment
saying precisely this.
Unlike the prior PR, this does not rename any files, which should reduce
the 'git noise' impact of this change.

_Thanks!_
