SECURITY: Update cabextract to 1.6.

It fixes CVE-2015-2060, a directory traversal vulnerability.
A CAB file with overlong UTF-8 encodings for "/" can get its files \ 
extracted to
an absolute path instead of the current directory. [Debian bug #778753]
Under Cygwin, a CAB file using both "/" and "\" can evade \ 
checks for absolute
files and "../" directory traversals and can get its files extracted to any
path.
