erts: Increase length of well formed header names from {packet,http}

To ease matching of unrecognized header field names we convert them
from case insensitive to the format Sec-Websocket-Version
with capital letters only first and after hyphens.

Earlier only header names up to 20 characters were converted to this
format due to internal buffer limitation. Raising this limit to 50
is a pragmatic solution for existing long header names such as
Sec-Websocket-Version, while valid header names longer than 50 characters
are not very probable.
