Only try to generate a config if the ESP is mounted

Browse source 
The posttran scriptlet attempts to generate a GRUB configuration if there
isn't one in the EFI System Partition. But this leads to a failure if the
grub2 package is installed in a container.

To avoid this issue, only attempt to generate a GRUB config if the ESP is
mounted in /boot/efi.
