[bazel] Use glibc 2.28 from Buster in toolchain
[bazel] Use glibc 2.28 from Buster in toolchain

Our Swarming machines still use Debian 10 (Buster). We do need
to run some executables locally (e.g. when re-generating files
in the CheckGeneratedFiles job), so we should compile and link
against an older version of glibc so they can work on those
machines with older OSes.
