wsrep sst scripts: removing extra blank lines and spaces

Browse Source 
Removed numerous extra blank lines and spaces that interfere with
reading and understanding program code, making it more difficult to
find errors in scripts. I also removed all extra trailing spaces at
the ends of lines, which lead to marking extra lines as changes
(in subsequent changes). The amount of indentation in some parts
of the code has also been normalized.
