Mark arguments to certain syscalls as being const

Mark arguments to certain system calls as being const where they should be but
aren't.  The list includes:

 (*) The filename arguments of various stat syscalls, execve(), various utimes
     syscalls and some mount syscalls.

 (*) The filename arguments of some syscall helpers relating to the above.

 (*) The buffer argument of various write syscalls.

  * execve(). This function needs to use IRET, not SYSRET, to set up all state properly.
  *
  * C extern interface:
- *       extern long execve(char *name, char **argv, char **envp)
+ *       extern long execve(const char *name, char **argv, char **envp)
  *
  * asm input arguments:
  *      rdi: name, rsi: argv, rdx: envp
  *
  * We want to fallback into:
- *      extern long sys_execve(char *name, char **argv,char **envp, struct pt_regs *regs)
+ *      extern long sys_execve(const char *name, char **argv,char **envp, struct pt_regs *regs)

  * do_sys_execve asm fallback arguments:
  *      rdi: name, rsi: argv, rdx: envp, rcx: fake frame on the stack
