libndr: Avoid assigning duplicate versions to symbols
Symbols _ndr_push_error and _ndr_pull_error keep getting redefined as
they are included without wildcard in abi_match. Apparently on linux ld
does not complain about duplicate symbols, but on freebsd ld fails to
link with following error:
[ 918/3912] Linking bin/default/librpc/libndr.so
ld: error: duplicate symbol '_ndr_pull_error' in version script
ld: error: duplicate symbol '_ndr_push_error' in version script
clang: error: linker command failed with exit code 1 (use -v to see invocation)
