Fix tools CI

[jw3]

The CI for the tools build runs on an older fedora to ensure it links to an older glibc, 2.27. It appears a recent GitHub actions change to node requires 2.28. So we are getting a

versionGLIBC_2.28' not found`

Two options:

1. bump glibc up to 2.28, which will exclude some older distros
2. checkout manually rather than using the checkout action

If (2) is done, will other actions have issues too?

From the workflow yaml

# 28 has glibc-2.27, compatible >= el8, fc, ubuntu 18.04

If I recall correctly the oldest glibc was 18.04. We can probably advance past that. If any good reason to support 18.04, then it can be revisited.

Probably the solution here is to just bump the fedora image up which ever one has 2.28, which is probably fedora:29.
