recipetool: create: avoid decoding errors with Python 3

We're opening source files with the default encoding (utf-8) but we
can't necessarily be sure that they are UTF-8 clean - for example,
recipetool create ftp://mama.indstate.edu/linux/tree/tree-1.7.0.tgz
prior to this patch resulted in a UnicodeDecodeError. Use the
"surrogateescape" mode to avoid this.

Fixes [YOCTO #9822].
