[PATCH v3 06/14] selftests/nolibc: stat_timestamps: remove procfs dependency

From: Zhangjin Wu
Date: Fri Jun 30 2023 - 10:49:24 EST


'/proc/self/' is a good path which doesn't have stale time info but it
is only available for CONFIG_PROC_FS=y.

When CONFIG_PROC_FS=n, use '/init' for initramfs and '/' for the others.
