Ticket #4549: subshell: call execl with argv[0] being the actual path to Bash. 

We currently call Bash with argv[0] being just the fixed string
"bash", but this confuses Bash when it initializes the shell variable
BASH, which are expected to be the absolute file path to the current
Bash image.  This patch fixes argv[0] to be the actual path that mc
uses to start Bash.
