Increase meta tag maxlength

Can we just remove it all together? The max-length is completely arbitrary bc this is not a storage limitation. Many site editors pack a TON of keywords (I know with little or no search engine impact) and this is really bogging us down.

This patch was from alpha6

The default value for #maxlength is 128, so we *need* this.

Leaving this on the backburner for now, the field can be altered using hook_form_alter() if need.

Actually I'm going to mark this as a duplicate of #1715262: Meta description too short, which has a patch file that increase the limit to 1024.
