[PATCH-2023.02.x] package/{glibc, localedef}: security bump to 2.36-117

Fixes the following security issues:

CVE-2023-4527: If the system is configured in no-aaaa mode via
/etc/resolv.conf, getaddrinfo is called for the AF_UNSPEC address
family, and a DNS response is received over TCP that is larger than
2048 bytes, getaddrinfo may potentially disclose stack contents via
the returned address data, or crash.

CVE-2023-4806: When an NSS plugin only implements the
_gethostbyname2_r and _getcanonname_r callbacks, getaddrinfo could use
memory that was freed during buffer resizing, potentially causing a
crash or read or write to arbitrary memory.

CVE-2023-5156: The fix for CVE-2023-4806 introduced a memory leak when
an application calls getaddrinfo for AF_INET6 with AI_CANONNAME,
AI_ALL and AI_V4MAPPED flags set.
