[PATCH v1 10/17] selftests/nolibc: rename euid0 variable to is_root

From: Zhangjin Wu
Date: Wed Jun 21 2023 - 09:06:33 EST


More conditional variables will be added, let's rename them with more
meaningful 'has_' or 'is_' prefix.

euid0 is converted to is_root to indicate whether or not running as
root.
