 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
