fix: Add missing 'pselect6_time32' and 'ppoll_time32' syscall overrides

fix: Add missing 'pselect6_time32' and 'ppoll_time32' syscall overrides

The instrumentation currently has overrides to the generated syscall
tracepoints of 'ppoll' and 'pselect6' to extract additional information
from the parameters.

On arm-32 and x86-32 these 2 syscalls were renamed to 'ppoll_time32' and
'pselect6_time32' and new syscalls using 64-bit time_t were introduced
with the old names. This results in missing overrides on these
architectures for the 32-bit variants that were renamed.

Add the '_time32' overrides to restore the previous behavior.
