[libgomp, testsuite] Reduce recursion depth in declare_target-*.f90
When running the libgomp testsuite with GOMP_NVPTX_JIT=-O0 using an nvptx
accelerator (Nvidia T400, 2GB), I run into:
...
libgomp: cuCtxSynchronize error: unspecified launch failure \
(perhaps abort was called)
libgomp: cuMemFree_v2 error: unspecified launch failure
libgomp: device finalization failed
FAIL: libgomp.fortran/examples-4/declare_target-1.f90 -O0 execution test
...
The test-case contains:
...
! Reduced from 25 to 23, otherwise execution runs out of thread stack on
! Nvidia Titan V.
if (fib (23) /= fib_wrapper (23)) stop 2
...
Fix this by reducing the fib/fib_wrapper argument from 23 to 22.
Same for declare_target-2.f90.
Tested on x86_64 with nvptx accelerator.

* testsuite/libgomp.fortran/examples-4/declare_target-1.f90: Reduce
recursion depth.
* testsuite/libgomp.fortran/examples-4/declare_target-2.f90: Same.
