[compiler-rt] [ASan] Limits the conditions of the deadlock patch (PR #137127)

[via llvm-commits]

https://github.com/Camsyn created https://github.com/llvm/llvm-project/pull/137127

PR #131756 introduced a patch to fix a deadlock between LSan and ASan.

The relevant deadlock only occurs when LSan is enabled and `dl_iterate_phdr` is used for Stop-the-World, i.e., under the condition `CAN_SANITIZE_LEAKS && (SANITIZER_LINUX || SANITIZER_NETBSD)`.

Therefore, this commit also sets the effective condition of this patch to the above condition, avoiding unnecessary problems in other environments, e.g., stack overflow on MSVC/Windows.

`dl_iterate_phdr` is used for Stop-the-World, i.e., under the condition
