meson: pass --no-pager to meson configure command

The `meson configure` command is used in `.gitlab-ci/meson/build.sh` to
show a summary of the build configuration, however when the script is
re-used locally on systems when there is a pager the commands blocks
for user input, which can be annoying.

Pass the `--no-pager` option to `meson configure`, so that it never
blocks for user input.

This does not change the behavior in the CI, it just makes the script run
uninterrupted also on local invocations.
