ompi/tools/wrappers/ompi_wrapper_script.in: fix dynamic library logic

When open-mpi is compiled with script wrapper compilers option:

    ./configure --enable-script-wrapper-compilers ...

The generated wrappers (e.g. mpicc) emit warnings:

    Use of uninitialized value $have_dynamic in numeric eq (==) at ./mpicc line 206.

Commit 1f18b20
"wrappers: Improve static library handling" removed the declaration of
the variable "$have_dynamic" but did not removed all its occurrences.

This commit fixes this issue by removing this leftover variable.
