Commit d7ef97a013
("[build] Fix oss-fuzz build with the dataflow sanitizer") broke
build inside Linux-kernel after 'import', as it no longer can
conditionally remove ZSTD_MEMORY_SANITIZER definition from
the #if DEF_A || DEF_B block. This emits -Wundef warning which
can be treated as error.
Split this preprocessor condition into two separate conditions
to fix this.

The mentioned path is being created/used by the 'import' rule for
generating source files for Linux kernel.

Commit a5f2c45528 ("Huffman ASM") added a new ASM source file,
but it wasn't added to the kernel Makefile despite that it received
support for Huffman ASM according to the internal definitions. This
leads to undefined references, as huf_decompress.o now calls those
ASM functions.
Add it to the list of sources when building inside the kernel tree.
Kbuild can handle .S files just fine, so none additional rules
needed.

Linux 5.15 introduces a new Kconfig option, CONFIG_WERROR, which
forces -Werror for the entire kernel.
Current in-kernel ZSTD implementation uses functions deprecated
in 1.5.0, and thus fails on -Wdeprecated-declarations.
Turn this particular error into warning to be able to build the
kernel with CONFIG_WERROR. I'm not disabling them completely to
make sure they'll be visible and [hopefully] fixed sooner or later.
