Add search paths for 32-bit Boost on Fedora

This will also cause the 64-bit version of the library to be picked up
on any distro that's not based on Fedora, which may cause some confusing
problems.

Is there a right way to do this? Meson doesn't allow you to override the
library search path for part of the build, and it also can't
differentiate between 32-bit and 64-bit libraries by default.
