That commands do not used glibc.
brctl has own functions, arp used /proc/net/arp (IADM).

First, it's not so hard to parse one zero instead of two zeroes by Perl.
Perl has powerful regexps to do that.
Second, I prefer to print out by %2.2X modifier too, but the functions used
from glibc NSS part. Ask to glibc-devel maillist about.

It has reason to leave it "as is" for compatibility.
That's because I has intention to use /etc/ethers database by ebtables
for name usage instead of full MAC-address.
