data: switch gdm.service.in to use cmake format

We're going to be switching to meson, and meson doesn't
deal too well with an @ in the configuration file that's not
part of a substitution variable.

This commit switches the gdm service over to use a cmake style
of substitution variables, so we can later tell meson to use
configure in cmake mode and workaround the @ confusion.
