ci: fix Valgrind startup failure on Arch via DEBUGINFOD_URLS

Browse Source 
Arch Linux ships a stripped ld-linux-x86-64.so.2, so Valgrind cannot
find the memcmp/memcpy/strlen symbols it must redirect and exits at
startup with "Fatal error at startup: a function redirection which is
mandatory for this platform-tool combination cannot be set up".

debuginfod is already installed in the image but was never wired up.
Set DEBUGINFOD_URLS to the official Arch debuginfod server so Valgrind
fetches the missing glibc debug symbols on demand and caches them.
