60ce9bdf introduced a local reimplementation of ZSTD_isFrame to this
tree, as the definition in libzstd is only available for static linking.
When a static build of libzstd is in-fact available to kexec-tools, this
was previously causing multiple-definition errors at link time.
prefer the ZSTD_isFrame from libzstd, if it's available, by adding
__attribute__((weak)) on the local definition.
