imagebuilder: properly escape single quotes in device titles

The name "Plat'Home OpenBlocks AX3" causes the imagebuilders "make info"
command to fail with:

    bash: -c: line 0: syntax error near unexpected token `('
    bash: -c: line 0: `echo;  [...]'
    Makefile:99: recipe for target '_call_info' failed

Properly escape single quotes to avoid breaking the echo commands.
