unit tests: fix test failures "The param /boot/boot/vmlinuz-xxx is incorrect"

Browse Source 
Currently, some tests failed with "The param /boot/boot/vmlinuz-xxx is
incorrect", for example,

    [root@fedora kexec-tools]# shellspec spec/kdumpctl_manage_reset_spec.sh
    Examples:
      1) kdumpctl reset-crashkernel [--kernel] [--fadump] Test the kdump dump mode  --kernel=ALL kdumpctl should warn the user that crashkernel has been udpated
         When call reset_crashkernel --kernel=ALL

         1.1) The error should include Updated crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M for kernel=/boot/vmlinuz-5.15.6-100.fc34.x86_64

This happens because when a system has a boot partition, grubby
automatically prefixes a path with "/boot". The current boot loader
entries used for tests already has the prefix "/boot" in the path and
prefixing a path again will cause the above problem.

grubby uses "mountpoint -q /boot" to tell if there is a boot partition.
This patch mocks mountpoint so grubby knows the boot loader entries
are for a system without a boot partition.

Note this patch also avoids another error seen in the setup phase of the
test "The param /boot/vmlinuz-xxx is incorrect". I believe this error is
a bug of "grubby --update-kernel" in testing mode because running the
grubby in normal mode actually works and "grubby --info=/boot/vmlinuz-*"
also works in testing mode,

    [root@fedora support]# grubby --no-etc-grub-update --grub2 --bad-image-okay --env=grub_env -b boot_load_entries --args crashkernel=333M --update-kernel=/boot/vmlinuz-5.15.6-100.fc34.x86_64
    The param /boot/vmlinuz-5.15.6-100.fc34.x86_64 is incorrect

    [root@fedora support]# grubby --no-etc-grub-update --grub2 --bad-image-okay --env=grub_env -b boot_load_entries --info=/boot/vmlinuz-5.15.6-100.fc34.x86_64
    index=0

    [root@fedora support]]# grubby --args crashkernel=333M --update-kernel=/boot/vmlinuz-6.0.7-301.fc37.x86_64 && echo "succeed"
    succeed
