[runcard] in CODEGEN, backport gg_tt.mad: fix/hardcode USEBUILDDIR=1 …

…(and propagate FPTYPE from make_opts) in _link targets for madgraph5#945

The only files that still need to be patched are
- 3 in patch.common: Source/makefile, Source/genps.inc, SubProcesses/makefile
- 3 in patch.P1: auto_dsig1.f, driver.f, matrix1.f
