zipl: add an ability to specify components location

Browse Source 
When creating a bootmap, look for zipl components (stage3.bin and
zipl helpers) in a directory specified by S390TOOLS_LIBDIR shell
environment variable. If that variable is not set, then look for
them at the default location.

In verbose mode print the name of s390-tools library directory,
where the search was implemented.
