create-pull-request: cd to relative directory
create-pull-request -d path creates empty patches if directory
is specified as a path, i.e. ./bitbake or ./bitbake/ or full path.
It behaves expected way only if script is run with -d bitbake, i.e.
relative dir name doesn't contain '\'.
Fixed this unwanted behaviour by changing directory and running
git format-patch in it with --relative, without specifying
relative path as a parameter.
