swab.3: SYNOPSIS: Use 'restrict' in prototypes

Both POSIX and glibc use 'restrict' in swab().
Let's use it here too.

.../glibc$ grep_glibc_prototype swab
posix/unistd.h:1147:
extern void swab (const void *__restrict __from, void *__restrict __to,
		  ssize_t __n) __THROW __nonnull ((1, 2))
    __attr_access ((__read_only__, 1, 3))
    __attr_access ((__write_only__, 2, 3));
.../glibc$
