[PATCH] hob: ensure error message text is properly escaped

[Paul Eggleton <paul.eggleton@linux.intel.com>]

Our poor implementation of markup escaping was causing invalid
markup, leading to the error dialog being blank. Use the glib markup
escaping function provided by PyGTK+ to do this properly and avoid the
blank error dialogs.

Partial fix for [YOCTO #2983].
