This commit uses the new `libx52_check_feature` API to check if the
device supports LED control. If not, it prints an error message and
exits the LED tests gracefully.
This also reverts commit 45f009ac90, which
had moved the LED tests to the end. Since this is no longer necessary,
it is moved back to avoid any issues with anything that may have relied
on the old order.
This change updates x52test to use the gettext APIs. This also adds a
fake message catalogue to verify that the code is converted correctly
and the translations are displayed.
The fake message catalogue translates the English strings into Pig
Latin, which makes it easy enough for a maintainer to verify that the
changes have been made correctly.
Finally, this also adds some documentation to tell the maintainer or
translator how to make the relevant changes.
