FBSD: allow exclusion of kernel symbols

Gerrit/5503 added support for kernel module symbols in the
bsd.kmod.mk world; however, the inclusion of symbols is conditoinal
on the DEBUG_FLAGS make variable being *set*, as opposed to nonempty.
So we must use an intermediate variable to store the AC_SUBST
result and conditionalize assignment to DEBUG_FLAGS on whether
or not it is empty.
