os/user: use os.UserHomeDir for user.HomeDir

Browse Source 
Using os.UserHomeDir for user.HomeDir helps us deduplicate the
logic and keep the behavior consistent.

Also make os.UserHomeDir return "/sdcard" in android.

See: https://go-review.googlesource.com/c/go/+/37960/1/src/os/user/lookup_stubs.go#48

Fixes #31070
