Limit SMP-only symbols to SMP-enabled builds in gensymbol

gensymbol was updated in OpenMathLib#5594 to support the
openblas_set_threads_callback_function symbol. This caused SMP-disabled
builds to regress as openblas_set_threads_callback_function is only
defined when SMP is enabled. Update gensymbol to only define
openblas_set_threads_callback_function when SMP is enabled in the build.
