5a668bdb - [libc] Migrate sys/epoll tests to use ErrnoCheckingTest. (#132823)

[libc] Migrate sys/epoll tests to use ErrnoCheckingTest. (#132823) This is similar to PR #132107 but for tests for sys/epoll.h functions. ErrnoCheckingTest ensures that errno is properly reset at the beginning of the test case, and is validated at the end of it, so that the manual code such as the one proposed in PR #131650 would not be necessary.
