testsuite: Increase delay in conc059

As noted in #19179, conc059 can sometimes fail due to too short of a
delay in the its Haskell threads. Address this by increasing the delay
by an order of magnitude to 5 seconds.

While I'm in town I refactored the test to eliminate a great deal of
unnecessary platform dependence, eliminate use of the deprecated
usleep, and properly handle interruption by signals.

Fixes #19179.
