Add Solaris support for <isc/endian.h>

While Solaris does not support the nonstandard hto[bl]e{16,32,64}() and
[bl]e{16,32,64}toh() conversion functions, it does have some
byte-swapping macros available in <sys/byteorder.h>.  Ensure these
macros are used in the fallback definitions of the aforementioned
nonstandard functions.
