(PUP-3631) Allow bff security update packages with nim package provider

This commit adapts the regular expression used in the `nim` package
provider to allow packages with `S` (security update) in their header to
be installed instead of throwing error as previously with `Unable to
parse output from nimclient showres: line does not match expected
package header format` as message.
