[PATCH] fix grub-install efibootmgr presence test with --removable

[Leif Lindholm]

When executed for an EFI target, grub-install checks for the path of
efibootmgr - however, this utility is not required (or used) when
installing to a removable media (with --removable).

However, since grub-install does "set -e", the absence of efibootmgr
on the system causes the install script to exit with an error code,
without any message, after a successful installation.

(Found because I'm doing EFI builds on my chromebook.)

Trivial patch attached.
