[PATCH] linux-custom: add -e option to postinstall script

[PATCH] linux-custom: add -e option to postinstall script

[srinuvasan.a via isar-users]

From: Srinuvasan A <srinuvasan.a@siemens.com>

While inspecting the kernel package, a warning was observed related
to the postinstall script. It appears the script was not using the
`-e` option, which ensures the script stops immediately upon any error.

To fix this warning, add the -e option to the postinstall script,
similar to how other maintainer scripts have it.

Logs:
W: linux-image-cip: maintainer-script-ignores-errors [postinst]
