Remove accidentally added gfortran.dg/gomp/allocate*-.f90 files

Remove accidentally added gfortran.dg/gomp/allocate*-.f90 files

I looked at the commit, proof reading the commit, but missed
a <tab> in the changelog, fixing it with 'git ... --amend',
the new files sneaked in - and the auto-accept new files
without ChangeLog entry feature let it pass.

Hence, remove those bogus files again that were added
in r14-1299-g366e3d30b8d5dc2bf226696987dfbd2a7df192f5
