ANDROID: kasan: fix has_attribute check on older GCC versions

A previously backported commit 8712cc72 ("BACKPORT: kasan: add
CONFIG_KASAN_GENERIC and CONFIG_KASAN_SW_TAGS") introduced a
__has_attribute(__no_sanitize_address__) check into
include/linux/compiler-gcc.h. Unfortunately older GCCs (before version 5)
don't support support this macro, which results in a compilation error.

Fix by checking GCC version instead. The same fix was applied to the 4.14
common kernel during the backport, but was forgotten here.
