Remove altgr rules for Удмурт ALTT

The rules are not required since the input is same as output.
In such conditions jquery.ime will not consume the keypress causing
normal keypress effects.

Also removing a condition about not consuming keypress event added
for this in commit 49d02b602cf303dfde3ca4bb2f509c7a3a44364c
