perf(binary): batch file type checks in find

[soimkim]

Summary

• Keep the same find paths and filters in find_binaries_from_out_dir.
• Run file on many paths per process (-exec file {} +) instead of one process per file.

Test plan

• system/fonts, system/bin, and system/lib64 return the same paths as file {} \;.
• root/ still does not apply the .odex exclusion used for system/.
• Android 17 scan still skips a missing search directory instead of running find on it.
