package/boost: drop versioned layout

boost.m4 embedded by cc-tool is not able to find boost libraries when
they are versionned (e.g. libboost_program_options-gcc9-mt-sd-1_78.a):

configure: error: cannot find the flags to link with Boost program_options

azmq and i2pd also have the same issue:

CMake Error at /nvmedata/autobuild/instance-8/output-1/host/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:165 (message):
  Could NOT find Boost (missing: Boost_INCLUDE_DIR system date_time thread
  chrono random) (Required is at least version "1.48")

So drop versioned layout option
