Error with tools/bazel_in_docker.sh if username == groupname

[vfdev-5]

Following code:

serving/tools/bazel_in_docker.sh

Lines 48 to 49 in 28d1c0d

	local cmdline="groupadd -f ${groupname} && groupmod -o -g ${gid} ${groupname}"
	cmdline+="; id -u ${username} &>/dev/null || useradd ${username} && usermod -o -u ${uid} -g ${gid} ${username}"

will produce the error:

useradd: group user exists - if you want to add this user to that group, use -g.
chroot: invalid user

if username and groupname are the same.

EDIT: A simple solution can be to add -N:

 cmdline+="; id -u ${username} &>/dev/null || useradd -N ${username} && usermod -o -u ${uid} -g ${gid} ${username}"
