Update Lithuanian keymaps

[rq]

The Lithuanian keymaps that currently exist in Haiku are a bit messy. They were all assembled by Antanas Buckus (previous Haiku localizer to Lithuanian), but not only their naming is a bit unusual, but also their contents.

The patch that I will attach sanitizes two of the Lithuanian keymaps (called "Lithuanian" and "Lithuanian (Standard)"). It removes the crap from the Opt layer in Lithuanian Standard, adds a few characters to the Option layer in both layouts and fixes the command key positions to Haiku's defaults (which I personally dislike, but whatever).

BEFORE applying the patch however, please rename the layouts as follows:
Lithuanian (Ergonomic).keymap -> Lithuanian (Buckus).keymap
Lithuanian.keymap -> Lithuanian (Standard).keymap
Note: you may want to commit these two renames separately from the third in order for git to actually understand what happened. Without commiting, it will see Lithuanian (Standard).keymap as a new file
Lithuanian (Baltic).keymap -> Lithuanian.keymap

Renaming before patching is important, because I want to change the default (to the one used in all other OS's) and then patch it. I am also renaming "Lithuanian (Ergonomic)" to "Lithuanian (Buckus)", because there is at least one more Lithuanian "Ergonomic" layout that I am aware of (see ​http://lekp.info/), which is drastically different from what Antanas has created. I'd rather use author's name for this one.
