tests: avoid checking the exitcode of false

Solaris false returns 255 instead of 1, so we remove one unneeded instance and
replaces another with (exit 1) as suggested by Brodie Rao.

Simple commands:

  $ echo foo
  foo
  $ printf 'bar\nbaz\n' | cat
  bar
  baz

Multi-line command:

  $ foo() {
  >     echo bar
  > }
  $ foo
  bar

Regular expressions:

  $ echo foobarbaz
  foobar.* (re)
  $ echo barbazquux
  .*quux.* (re)

Globs:

  $ printf '* \\foobarbaz {10}\n'
  \* \\fo?bar* {10} (glob)

Literal match ending in " (re)":

  $ echo 'foo (re)'
  foo (re)

Exit code:

  $ (exit 1) 
  [1]
