[pacman-dev] [PATCH 2/2] Revert "ci: cache packages"

[Emil Velikov]

This reverts commit e348ba38814c9cc7c1c9892d0451096234dc39ab.

With the above commit we started caching the downloaded packages. Based
on some testing and, it saves ~30s in the "step_script" stage while
adding 18s for "Restoring/Saving cache". A net saving of ~10s.

With earlier commit, we no longer use an ancient image which also pulls
base-devel - thus the packages we have to download is minimal.

Now comparing the uncached "step_script", vs the cached one - it is
slowed by 2-3 seconds (1:01 -> 1:03), while we eliminate the 18s (and
growing) caching.

Tl:Dr: With up-to date image, package caching in not worth it - be that
time, disk or network wise.
