Disable DeprecatedOrUnsafeBufferHandling analyzer check

When compiling with C11 or later, this check suggests to use C11 Annex K
functions like memcpy_s. These functions aren't widely supported.

We will lose some warnings about really dangerous functions like
sprintf, but this check doesn't offer more granularity, see
llvm/llvm-project#64027.
