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

_update_kernel_cmdline handles two cmdline parameters at once. This does not
only make the function itself but also its callers more complicated than
necessary. For example in _update_crashkernel the fadump gets "updated" to
the value that has been read from grubby. Thus simplify
_update_kernel_cmdline to only update one parameter at once.
While at it shorten some variable named in the callers.
