panda: install-binaries: work with current e2fsprogs

Start trapping errors after partition autodetection.

Needed for current e2fsprogs because e2label throws
an error these days when used on a swap partition

If a relevant error occurs during autodetection,
that is caught anyway (device not set), so this
won't cause any regressions.
