runtime: fix timespec definition on 32bits systems
The nsec field of timespec is a C long even when using
64bits time on 32bits systems.
This is because by timespec API if nsec never holds more than a
second worth of nanoseconds.
If it would theses would increment the sec field while the nsec
field would get the amount of nanoseconds modulus a second.
Fixes #77934
