Linus,

Fix issues with grub2bls in ktest.pl

ktest.pl does not know about grub2bls that was introduced in Fedora 30,
and now it does.

    ktest.pl: Fix incorrect reboot for grub2bls
    
    This issue was first noticed when I was testing different kernels on
    Oracle Linux 8 which as Fedora 30+ adopts BLS as default. Even though a
    kernel entry was added successfully and the index of that kernel entry was
    retrieved correctly, ktest still wouldn't reboot the system into
    user-specified kernel.
    
    The bug was spotted in subroutine reboot_to where the if-statement never
    checks for REBOOT_TYPE "grub2bls", therefore the desired entry will not be
    set for the next boot.
    
    Add a check for "grub2bls" so that $grub_reboot $grub_number can
    be run before a reboot if REBOOT_TYPE is "grub2bls" then we can boot to
    the correct kernel.
