testsuite: robustify check_* invocation of examples meta
testsuite/systemtap.examples/
* check.exp (extract_tag): Log extracted tags. Tolerate embedded '$'.
(run_command): Pass through commands to sh -c without eval quoting.
* README: Document "sh -c"-ness of check_* tags.
* *.meta: Fix quoting, add a few check_support predicates.
