package/dhcp: disable backtrace on internal bind
Like was done in 700674b45c86 (package/bind: disable backtrace support)
for the up-to-date, official, upstream bind, also disable backtrace on
dhcp's internal bind to avoid the following build failure since commit
0c8dd6ebd656 (package/dhcp: use internal bind):
/nvmedata/autobuild/instance-15/output-1/host/lib/gcc/armeb-buildroot-linux-uclibcgnueabi/10.3.0/../../../../armeb-buildroot-linux-uclibcgnueabi/bin/ld: /nvmedata/autobuild/instance-15/output-1/build/dhcp-4.4.3/bind/bind-9.11.36/lib/isc/.libs/libisc.so: undefined reference to `_Unwind_GetIP'
