ANDROID: drivers: debug_kinfo: drop KALLSYMS_BASE_RELATIVE reference

Browse Source 
Commit 64e166099b ("kallsyms: get rid of code for absolute kallsyms")
dropped support for KALLSYMS_BASE_RELATIVE which is leading to below
error in downstream drivers:

	pc : debug_symbol_available
	lr : debug_symbol_available
	Call trace:
	debug_symbol_available
	init_module
	do_one_initcall
	do_init_module
	load_module
	__arm64_sys_finit_module
	invoke_syscall
	el0_svc_common.llvm.7307617742197862454
	do_el0_svc
	el0_svc
	el0t_64_sync_handler
	el0t_64_sync

Fix the error by removing reference to KALLSYMS_BASE_RELATIVE and drop
the functionality under it.
