Fix a regression causing the portal helper to crash.
In 94423151b2 we moved the dbus interface
descriptions into seperate files which is why we had to include the
fileUtils js module. This module imports the params js module, so add
params.js to the gresources file for the portal helper.
Using a single resource file for all JS sources saves a couple of
build system instructions, but has some serious downsides:
- bundling the entire shell code with the tools blows
up their size unnecessarily
- the tools are rebuilt unnecessarily for any shell
code change
Autotools was painful enough to let this slip, but with meson we
don't have any excuses - using the actual dependencies speeds up
the build a tiny bit and reduces the tools' sizes from over 2M
to about 50k.
