package/uhd: propagate toolchain bug 64735 dependency from boost-thread

boost-thread needs std::current_exception since version 1.71.0 and
https://github.com/boostorg/exception/commit/386f5507cb8ec99c03ca535bea4f8bd61e0de910

std::current_exception depends on !BR2_TOOLCHAIN_HAS_GCC_BUG_64735 as a
result, uhd fails to build on:

So add a dependency to !BR2_TOOLCHAIN_HAS_GCC_BUG_64735
