ldbl-opt: Reuse argp tests that print long double

The test case tst-ldbl-argp checks that the conversion specifier '%Lf'
correctly prints long double values with the default long double format
for a platform.  This patch reuses the test case for long double with
the same format as double (-mlong-double-64).

Tested for powerpc, powerpc64 and powerpc64le.
