fix(bootstrap): force a system update before installing Hanzo

[palazzem]

Overview

Fixes an issue that prevents the system to run because GLIBC was missing. This regression has been introduced as Hanzo didn't take in consideration possible changes in archlinux:base-devel container. The reported issue was

# While building the Hanzo container
# [...]
(4/4) Warn about old perl modules
WARNING: '/usr/lib/perl5/5.38' contains data from at least 3 packages which will NOT be used by the installed perl interpreter.
 -> Run the following command to get a list of affected packages: pacman -Qqo '/usr/lib/perl5/5.38'

Downloading/Updating Hanzo...
sh: line 63: cd: /tmp/tmp.5UpXDaRZjD/hanzo: No such file or directory

/tmp/tmp.5UpXDaRZjD/hanzo folder didn't exist because git was failing with error:

sh-5.1# git
git: /usr/lib/libc.so.6: version `GLIBC_2.38' not found (required by git)

Updating the system before running Hanzo, solved the problem.
