grub-mkconfig contains the bashism `$EUID`, while in standard POSIX shell it should be `$(id -u)`. This breaks the script on systems where /bin/sh is not symlinked to bash, especially on systems where /bin/sh is dash, because `$EUID` does not work in dash.

The script has a fallback to use `id -u` in case EUID is not set.
