Another garnome on Solaris x86 issue - scrollkeeper bug

[Carson Gaspar <carson+garnome taltos org>]

An additional problem - scrollkeeper uses the completely non-standard 
strndup() function in libs/i18n.c. Folks seem to assume everyone runs Linux 
- ah well. The following patch should be equivalent, if I read the strndup 
man page correctly. The patch assumes strlcpy() is available - it really 
should be a configure test, or use strncpy() and explicitly null terminate, 
but I'm feeling lazy. And yes, I may return NULL pointers, but only if the 
original code would. Blech - I feel slimy...
