Collect unknown chunks in new chkcat 'unknown' which gets treated like
'misc', but isn't mangled on sparc-*-solaris2 because of function
definitions in C-headers like <pwd.h>. This shouldn't affect any
other platform since this was already a border-case.

Closes SF Bug 1012521 "getUserEntryForID dies".
Please merge.
