The POSIX alias takes (attr, int), returns EINVAL (22) for a null or
uninitialized attribute like the other pthread_attr setters, and
stores the value through scePthreadAttrSetsolosched, returning its
result in errno form. The signature and the stored int follow the SCE
twin in KytyPS5 and sharpemu; PS5PCEM implements the alias the same
way. The value is not applied to scheduling, recorded in TechnicalDebt.
Returnal (PPSA01285 v03.000.005) stops on it after eager binding

scePthreadAttrGet wrote priority 700 and left the affinity of the
destination untouched, whatever the thread was created with or set to
afterwards. It now reports the values the thread holds, as
pthread_attr_get_np already does.
