Fix bad '... \\' escape in ghcversion.h generation
Today I learned about the peculiarities of escaping within
single-quotes:
Turns out,
echo 'foo \\'
emits
foo \\
rather than escaping the '\'. Curiously, if you need to escape a '
within single-quotes, here's how to do it
echo 'foo '\'' bar'
which will emit
foo ' bar
This fixes #10002
