flock expects a real command as argument, not a shell function, so the
scripts are currently broken:
flock: failed to execute container_exec: No such file or directory
This patch defines the JENKINS_FLOCK helper variable which is expanded
by the remote_exec() shell helper.

In order to be able to remove old workspaces, this patch uses flock to
make sure the renaming for $dir to $dir.bak does not happen while a
build is in progress.
To achieve that, both the renaming and the command executed by
docker-run.sh use this exclusive lock.
Unfortunately, this does not prevent race conditions with builds not
relying on docker-run.sh, so such builds should either use flock or
switch to using docker-run.sh.

Replace ${var:-default} with ${var-default}.
I learned something new about shell scripting today. From bash manual:
===
When not performing substring expansion, using the form described
below (e.g., ‘:-’), Bash tests for a parameter that is unset or null.
Omitting the colon results in a test only for a parameter that is
unset. Put another way, if the colon is included, the operator tests
for both parameter’s existence and that its value is not null; if
the colon is omitted, the operator tests only for existence.
===
The immediate problem I need to fix is handling of
host_aarchXX_excludecheck and host_x86_64_excludecheck parameters
in tcwg-buildfarm.sh. With ":-" syntax the empty ("null") values are
replaced by defaults, causing GCC testsuite to be ignored on aarchXX
hosts when "--host_aarchXX_excludecheck ''" is given.
There happens to be a single usage ":-" in ${rw:-rw} in
start-container-qemu.sh, where ":-" is actually needed.

When using "set -u" we get unbound variable failuer on empty arrays.
E.g., "set -u; arr=(); echo ${arr[@]}" will fail. We workaround by adding
"--" as first element to CONVERTED_ARGS and then referencing array as
"${CONVERTED_ARGS[@]:1}".
