Subject: [PATCH] selinux: Use 1UL for EBITMAP_BIT to match maps type

This patch modifies the definition of EBITMAP_BIT in
security/selinux/ss/ebitmap.h from 1ULL to 1UL to match the type
of elements in the ebitmap_node maps array.

This change does not affect the functionality or correctness of
the code but aims to enhance code quality by adhering to good
programming practices and avoiding unnecessary type conversions.
