Boost package: Fix iostream autodetect libraries (#12440)

Boost iostream autodetects the compression libraries libzstd and
liblzma outside of the Spack environment.

This commit disables mentioned libraries. In the future if the
Spack zstd/lzma packages were added as dependencies of the Spack
Boost package, additional work could be done to build Boost with
the Spack-built versions of these libraries.
