Subject: [PATCH] Linker: Fix incorrect test added in Ib9816d8b

The test was intended to check for whether we have a user ID *or* a user
name. Instead, it's checking if we have a user ID *and* a user name. And
it also failed to consider User:0.

Bug: T227656
Change-Id: Ia1b5c4a6ae028513b73a65cd2c885459327d29c3
