Instead of trying to read /proc/uptime, which is not allowed on Android, we patch procps to use the sysinfo(2) syscall to figure out the uptime. This should fix at least "ps -o etime".
Access to this file is prohibited on some devices by SELinux and causes utilities to treat /proc as not mounted. Related issues: * https://github.com/termux/termux-packages/issues/1625 * https://github.com/termux/termux-packages/issues/4132
