Add 50K'th line in the source code

As per current top commit (9c0c23c0) the amount of code in CRIU
_without_ the contents of the test/ directory is

$ git grep -l . | egrep -v ^test | xargs wc -l
...
49999

This is the only chance for such a great one-liner :)

The place in the code is not completely random -- it's one of the
few occurrences of two consecutive empty lines in a .c file.
