[Buildroot] [PATCH v2 1/2] pkg-generic.mk: reinstall targets

[Doug Kehn]

Add reinstall targets for host, target, staging, and images variants.
clean-for-reinstall targets added to remove package
.stamp_target_install file to allow package install.  Additionally, when
OVERRIDE_SRCDIR is provided, .stamp_rsynced is removed to ensure pakcage
is up to date before reinstalling.
