audit: fix macros warnings

Some unused macros could cause gcc warning:
kernel/audit.c:68:0: warning: macro "AUDIT_UNINITIALIZED" is not used
[-Wunused-macros]
kernel/auditsc.c:104:0: warning: macro "AUDIT_AUX_IPCPERM" is not used
[-Wunused-macros]
kernel/auditsc.c:82:0: warning: macro "AUDITSC_INVALID" is not used
[-Wunused-macros]

AUDIT_UNINITIALIZED and AUDITSC_INVALID are still meaningful and should
be in incorporated.

Just remove AUDIT_AUX_IPCPERM.

Thanks comments from Richard Guy Briggs and Paul Moore.
