Fix tests to work on Ubuntu (dash)

The system shell (/bin/sh) on Ubuntu is dash, which aims to be a
POSIX standard shell.  In particular, dash does not implement any
of the common extensions to the standard that, say, bash and ksh
do.

Replace some non-POSIX constructs in setup.sh with more portable
and mundane code.

 # Main functions:
 #   prepare_tests(description) - setup for testing, i.e. create repos+config
 #   run_test(description, script) - run one test, i.e. eval script
 #
 # Helper functions
 #   cgit_query(querystring) - call cgit with the specified querystring
 #   cgit_url(url) - call cgit with the specified virtual url

 # Example script:

 # . setup.sh
 # prepare_tests "html validation"
 # run_test 'repo index' 'cgit_url "/" | tidy -e'
 # run_test 'repo summary' 'cgit_url "/foo" | tidy -e'
