fix getopt[_long] clobbering of optopt on success
getopt is only specified to modify optopt on error, and some software apparently infers an error from optopt!=0. getopt_long is changed analogously. the resulting behavior differs slightly from the behavior of the GNU implementation of getopt_long, which keeps an internal shadow copy of optopt and copies it to the public one on return, but since the GNU implementation also exhibits this shadow-copy behavior for plain getopt where is is non-conforming, I think this can reasonably be considered a bug rather than an intentional behavior that merits mimicing.
