linux: Use the input_event_X macros to access input_event members

[snogge]

Description

Use the input_event_sec and input_event_usec members (macros in C) on all platforms, no matter whether time_t is 32 or 64 bits.
This means the same members are available in the struct no matter whether it is a 32 or 64 bit platform or the linux_time_bits64 config is set.

This is a breaking change.

Checklist

• Relevant tests in libc-test/semver have been updated
• No placeholder or unstable values like *LAST or *MAX are
  included (see #3131)
• Tested locally (cd libc-test && cargo test --target mytarget);
  especially relevant for platforms that may not be checked in CI

This is a breaking change and should not be backported to the 0.2 branch.
