devices: cmos: suppress deprecation warnings on time_t on musl

Browse Source 
The type is to change from 32-bit to 64-bit. See
https://github.com/rust-lang/libc/issues/1848.

The change is announced via a deprecation warning. Cloud Hypervisor's
code does not need changing. Simply suppress these warnings.
