scripts/contri*sh: no longer grep -v ' '

Originally these scripts filtered out names that have no space so that
they better avoid nick names not intended for credits. Such names are
not too commonly used, plus we now give credit even to those.

Additionally: non-latin names, like Asian, don't have spaces at all so
they were also filtered out and had to be manually added which made it
an error-prone operation where Asian names eventually easily fell off by
mistake.

Closes curl#11206
