Log Message:
-----------
lxc/attach: Detect EACCES from execvp and convert to 126 exit status

Before:

sudo lxc-attach -n test /etc/passwd ; echo $?
lxc-attach: test: ../src/lxc/attach.c: lxc_attach_run_command: 1841 Permission denied - Failed to exec "/etc/passwd"
255

After:

sudo lxc-attach -n test /etc/passwd ; echo $?
lxc-attach: test: ../src/lxc/attach.c: lxc_attach_run_command: 1841 Permission denied - Failed to exec "/etc/passwd"
126

Which better aligns with bash:

/etc/passwd; echo $?
bash: /etc/passwd: Permission denied
126
