Fix glibc version
When doing just keygen
in a fresh container I got errors fetching glibc. Checking the gitweb page, the glibc-2.38
tag points to SHA 36f2487f13e3540be9ee0fb51876b1da72176d3f.
I could not spot any glibc-2.38-4
tag though, so I might be barking up the wrong tree here (or maybe I need to bump to 2.38-5?).
