copperplate/regd: do not involve Cobalt before binding is done
Some early code in sysregd wants to set the regular scheduling policy
of the main thread prior to binding to the Cobalt core manually. Make
sure to force a libc call for this, instead of going through a Cobalt
syscall first.
Functionally speaking, the effect will be the same since
pthread_setschedparam() mirrors the request to the regular C library,
which is what we'll need eventually. However we won't receive the
scary warning about a syscall being denied for an unbound process from
the Cobalt core when debug mode is enabled, e.g.:
[Xenomai] syscall <7> denied to sysregd[22217]
