In the BLS files, the 'linux' and 'initrd' fields are relative to the
$BOOT directory. If $BOOT is a mount point of boot partition, 'linux'
and 'initrd' fields are relative to boot partition. If not, the paths
are relative to $BOOT directory of root partition.
zipl always starts searching at / regardless of partitions and mount
points.
This commit extends the semantics of target= field in zipl.conf to make
it as a second search path, besides /, for those 2 BLS fields.
See issues #69 for more details.

Add a command line option and configuration section keyword to control
the zIPL secure boot support. This option is named "secure" and can take
one of three values:
auto (default)
Write signatures if available and supported by the system.
1
Signatures are written independent of support indicated by the local
system. Also missing signatures for stage 3 and kernel IPL files
will result in an error.
0
No signatures will be written.

The BootLoaderSpec (BLS) defines a file format for boot configurations,
so bootloaders can parse these files and create their boot menu entries
by using the information provided by them [0].
This allow to configure the boot items as drop-in files in a directory
instead of having to parse and modify a bootloader configuration file.
If the /boot/loader/entries exists and there are BLS files there, then
these are parsed and configuration sections are added without the need
to have these in a zipl.conf file.
A different BLS directory can be specified from the command line using
the --blsdir option.
