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
