openssl fails on FPU emulation for powerpc

Provide machdep.fpu_present sysctl variable like other ports.

Userland can get informed that FPU is absent and emulated in software
(and calculation results may not be correct in bit-to-bit precision).

This variable should be useful even if we could fix FPU emulation;
it is much faster to skip FPU arithmetic in general, rather than
relying upon emulation by kernel via illegal instruction handler.
