fix(install): avoid apt-package uninstall failure during web dep install (#371)

Browse Source 
* fix(install): avoid apt-package uninstall failure on web deps

On a fresh Pi install, requests is installed via apt (python3-requests),
which ships no pip RECORD file. When pip later installs
google-api-python-client, its dependency tree pulls a newer requests and
attempts to uninstall the apt copy, failing with "uninstall-no-record-file"
and aborting the whole install at step 7 (web interface dependencies).

Add --ignore-installed to install_via_pip so pip lays the new version down
in /usr/local (shadowing the apt copy) instead of trying to remove an
apt-managed package. This resolves the failure for any transitive
dependency pip needs to upgrade over an apt-installed package, not just
requests.

* fix(install): also pass --ignore-installed for local rgbmatrix install

Keeps the rgbmatrix pip install consistent with install_via_pip so it
won't fail trying to uninstall an apt-managed dependency either.

--ignore-installed stops pip from trying to *uninstall* packages that were
installed by apt (e.g. python3-requests). Those Debian packages ship no
