[PATCH] strip: don't corrupt PE binary's section/file alignment

[Jan Beulich]

Section and file alignment are supposed to remain unaltered when PE
binaries are stripped. While this is the case when they're strip-ed
individually, passing multiple such files to strip would reset the
two values to their defaults in all but the first of those binaries.
