meson: fix broken oss-fuzz support

Browse Source 
Regression in original introduction in commit
198e532300.

Every meson file in the repository must have this variable set, to an
appropriate per-file value, in order to cater to the split buildsystem
design where the build files are stored in a subdirectory away from the
source code.

If ossfuzz is enabled, this file is processed and the missing value will
come from some other file instead, which may not be correct.

- Using default values, ossfuzz is enabled but no other subdirs are, other
  than of course lib, which has a coincidentally identical value, and
  everything works.

- If contrib is enabled, it will set the per-file variable to a value
  that is *not* coincidentally the same as ossfuzz.

- If examples is enabled, it will set the per-file variable to a value
  that is coincidentally the same as ossfuzz... and do so later than
  contrib.

So, if contrib is enabled but examples is not, then the ossfuzz
directory fails to process correctly and the build aborts. Fix this by
explicitly adding the correct per-file variable.
