package.bbclass: run pre/post installation/removal scriptlets using sh -e

This allows catching errors in the scriptlets which would otherwise
go unnoticed, e.g. this sequence:
====
bogus_command
proper_command
====
would work just fine without any visible warnings or errors.

This was previously done only for rpm packages; this patch replaces
the rpm-specific tweak with one that works for all package types.
