In case _GNU_SOURCE is undefined, as in eal_common_errno.c, it was not possible to include rte_os.h which uses cpu_set_t. This limitation is removed: if CPU_SETSIZE is not defined, cpu_set_t related definitions and functions are skipped. Note: such definitions are unneeded in eal_common_errno.c. Applications which do not define _GNU_SOURCE may miss cpu_set_t related features on musl. Such case is detected by RTE_HAS_CPUSET being undefined, so functions which depend on rte_cpuset_t will be unavailable. A missing include of fcntl.h is also added.
