[MiNT] [PATCH] getlogin() returns names truncated to 3 characters

[Vincent Rivière <vincent.riviere@freesbee.fr>]

Hello.

I noticed a a 13 years old bug.
The MiNTLib's getlogin() function currently returns names truncated to 3 
characters. It is obviously a bug due to a misuse of sizeof() using pointer 
instead of array.

Alan, please commit!
