cs2cs_emulation_setup: fix issue with non C-locale
in +towgs84 case, we use sprintf() with floating-point formatter to output
the ellipsoid parameters. For a locale with decimal separtor != dot, the
resulting string will not be parsed correctly by proj_atof(), leading to
wrong numeric result.
The fix is similar to the one done in pj_latlong_from_proj()
Note for later: if using C++, we could use a locale-independent formatting
solution to avoid such issue.
