Andrey Konovalov 78788c3ede kasan: simplify and clarify Makefile 
When KASAN support was being added to the Linux kernel, GCC did not yet
support all of the KASAN-related compiler options.  Thus, the KASAN
Makefile had to probe the compiler for supported options.

Nowadays, the Linux kernel GCC version requirement is 5.1+, and thus we
don't need the probing of the -fasan-shadow-offset parameter: it exists in
all 5.1+ GCCs.

Simplify the KASAN Makefile to drop CFLAGS_KASAN_MINIMAL.

Also add a few more comments and unify the indentation.
