test: Set catch_system_errors=no on boost unit tests

Summary:
Boost does not handle asserts well in unit tests. Encountering one causes
test_bitcoin to hang indefinitely. This may explain the occassional timeouts we're
experiencing in CI.

See https://www.boost.org/doc/libs/1_68_0/libs/test/doc/html/boost_test/utf_reference/rt_param_reference/catch_system.html

Backport of Core [[bitcoin/bitcoin#18183 | PR18183]]

Test Plan:
Introduce `assert(0);` into a unit test, then: `ninja check`
Pre-patch, `ninja check` hangs until killed (Ctrl+C).
Post-patch, `ninja check` errors out as expected.
