test,ci: fix [AM]San, disable ASLR (#4365)

The kernel that ships with the new Ubuntu 22.04 CI image seems to have a
PIE slide that is bigger than the sanitizer runtimes can handle.

It makes ASan fail with thousands of "AddressSanitizer:DEADLYSIGNAL"
warnings, and MSan error with complaints about memory accesses outside
known ranges. Disabling address space layout randomization fixes both.

This commit also fixes a small bug in the platform_output test where
the cgroups v1 logic did not handle the "unlimited quota" special case
properly. Ubuntu 20.04 still uses cgroups v1.

asan: fix some tests (#3323)

Previously they were just being run incorrectly, but nothing wrong with
the test itself. We were also interpreting an ASAN failure as TEST_SKIP,
so test failures would not actually be reported as CI failures.
