cmake: probe for a system 7-Zip/LZMA SDK before fetching
Requested by the openSUSE packager: distributions ship the SDK sources
(lzma-sdk-devel), so the vendored lzma1604.7z download is unnecessary
there. Probe WINUAE_LZMA_SDK_SYSTEM_PATHS (common /usr locations,
overridable) for an installed SDK source tree before falling back to
WINUAE_LZMA_SDK_DIR and the fetch. Candidates must provide the C
sources, not just headers, since the SDK is compiled into the build.
