apparmor: fix capability list generation
The file `common/Make.rules` uses the C preprocessor to generate a list of capabilities and address families in some headers. For some reason, the makefile escapes the hash in `#include` statements, rendering them inoperable and making the generated headers empty. Removing the escape causes these files to be populated.

No idea why this appears to be a regression.

Fixes #25548.

@CameronNemo or @the-antz please confirm that this change results in a functioning apparmor installation.
