fai-cd: drop dead code
lib/task_sysinfo: make sure device is a valid block device before acccessing it

Fails with:

| /usr/lib/fai/task_sysinfo: line 65: [: =: unary operator expected

when using fai-cd on Debian/wheezy.

Several scripts became bash scripts over time, adapt the list
to cover all files accordingly.
