Updated libraw packages fix security vulnerabilities

This update provides libraw 0.18.13 fixing at least the following security issues: LibRaw versions prior to 0.18.12 are vulnerable to an integer overflow in the internal/dcraw_common.cpp:parse_qt() function. An attacker could exploit this to cause an infinite loop via a specially crafted Apple QuickTime file (CVE-2018-5815). LibRaw versions prior to 0.18.12 are vulnerable to an integer overflow in the internal/dcraw_common.cpp:identify() function. An attacker could exploit this to cause an divide-by-zero and resultant denial of service via a specially crafted NOKIARAW file (CVE-2018-5816). libraw 0.18.13 adds fixes for: * possible stack overrun while reading zero-sized strings * possible integer overflow
