Update raspap.sudoers

The command launched here: https://github.com/smartmarmot/raspap-webgui/blob/4299d4d7ccfe1da42d7505a47ffa03ad542ddbc4/includes/openvpn.php#L153
is actually /bin/ln I've had to manually fix it on raspberry pi bullseye

[smartmarmot]

I've tested this on two freshly build bullseye and it fails when you enable one of the configurations, now this is fixed.
Anyway I think that most likely use the full path would be a better option so actually recode the web UI that calls the shell commands. What do you think about?

I wasn't able to repro this behavior on Debian 11 (bullseye).

From what I understand, PHP's system() call functions like the C version.

The PHP docs lack detail on this, but the POSIX / ISO C standard on which it's based uses examples without absolute paths. Probably for better portability(?)

The POSIX system() function passes string to the sh shell command for execution.
A string with TSO/E command line syntax:

command_name parm1 parm2 … 

Example:
system("user_pgm1 1234 abcd xyz");
