package/pcre: security bump to version 8.41

Removed patches 0003 & 0004, applied upstream.

Fixes the following security issues:

CVE-2017-7244 - The _pcre32_xclass function in pcre_xclass.c in libpcre1 in
PCRE 8.40 allows remote attackers to cause a denial of service (invalid
memory read) via a crafted file.

CVE-2017-7245 - Stack-based buffer overflow in the pcre32_copy_substring
function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to
cause a denial of service (WRITE of size 4) or possibly have unspecified
other impact via a crafted file.

CVE-2017-7246 - Stack-based buffer overflow in the pcre32_copy_substring
function in pcre_get.c in libpcre1 in PCRE 8.40 allows remote attackers to
cause a denial of service (WRITE of size 268) or possibly have unspecified
other impact via a crafted file.
