package/glibc: add proper CPE ID version detail

Browse Source 
As reported in bug 15895, the GLIBC_VERSION field having a value
looking like 2.38-27-g750a45a783906a19591fb8ff6b7841470f1f5701, it
prevents the CPE/CVE matching with the NVD database to work correctly.

This commit fixes that by defining GLIBC_CPE_ID_VERSION, derived from
GLIBC_VERSION, by extracting the base version.

Also, we update GLIBC_IGNORE_CVES to account for the CVEs that have
clearly been fixed between 2.38 and
2.38-27-g750a45a783906a19591fb8ff6b7841470f1f5701. There are a number
of other CVEs still affecting the glibc package, but they are not
related to this
2.38...2.38-27-g750a45a783906a19591fb8ff6b7841470f1f5701 range.

Fixes: #15895
