cacheflush.2: Update SYNOPSIS for glibc wrapper 

Glibc uses 'void *' instead of 'char *'.
And the prototype is declared in <sys/cachectl.h>.

......

$ syscall='cacheflush';
$ ret='int';
$ find glibc/ -type f -name '*.h' \
  |xargs pcregrep -Mn "(?s)^[\w\s]*${ret}\s*${syscall}\s*\(.*?;";
glibc/sysdeps/unix/sysv/linux/nios2/sys/cachectl.h:27:
extern int cacheflush (void *__addr, const int __nbytes, const int __op) __THROW;
glibc/sysdeps/unix/sysv/linux/mips/sys/cachectl.h:35:
extern int cacheflush (void *__addr, const int __nbytes, const int __op) __THROW;

extern int cacheflush (void *__addr, int __nbytes, int __op) __THROW;
glibc/sysdeps/unix/sysv/linux/csky/sys/cachectl.h:30:
extern int cacheflush (void *__addr, const int __nbytes,
		       const int __op) __THROW;
