parallel-checkout: avoid dash local bug in tests
Dash bug https://bugs.launchpad.net/ubuntu/+source/dash/+bug/139097
lets the shell erroneously perform field splitting on the expansion of a
command substitution during declaration of a local variable. It causes
the parallel-checkout tests to fail e.g. when running them with
/bin/dash on MacOS 11.4, where they error out like this:
./t2080-parallel-checkout-basics.sh: 33: local: 0: bad variable name
That's because the output of wc -l contains leading spaces and the
returned number of lines is treated as another variable to declare, i.e.
as in "local workers= 0".
Work around it by enclosing the command substitution in quotes.
