This detects available hash-function/checksum binaries/executables by searching in "/system" for files whose names contain "sum" and creates an array out of that list.
Works on any device (but "find" cmd is supported since A6-M) but it's only useful for:
1) "special" or "unique" systems that could have an extra hash F that doesn't appear on this list: chromium.googlesource.com/aosp/platform/system/core/+/refs/heads/upstream/shell_and_utilities
2) Root users if they install or uninstall checksum bins and want to remember the available ones.
3) Flow that needs to correctly detect available hashers without relying on the previously mentioned list and without checking Android version
