Fix crashing CI

[sarlinpe]

• COLMAP recently switched to Metis: colmap/colmap@29a1e36
• Running the CI on every branch creation is unnecessary

Hi @skydes, thanks for the PR. It looks like the brew install of metis is appropriately installing the dependencies, but on linux, the metis library is not found. Is this what you're seeing? I suppose we may need to pass a flag like METIS_INCLUDE_DIRS?

I'm seeing:

Loaded plugins: fastestmirror, ovl

No package build-essential available.
Error: Not tolerating missing names on install, stopping.

on the yum install, so yum isn't installing anything, perhaps

It seems that yum fails on most package installs, currently looking into this.

@johnwlambert I cleaned up the yum installs. It previously failed to install suitesparse for Ceres.

Very nice work @skydes, thanks for cleaning that up.
