Fix Tramp rounding of file sizes and inode numbers

* lisp/net/tramp-sh.el (tramp-perl-file-attributes)
(tramp-perl-directory-files-and-attributes)
(tramp-do-file-attributes-with-stat)
(tramp-do-directory-files-and-attributes-with-stat):
Format file sizes and inode numbers without trailing ".0",
to avoid rounding errors when absolute values exceed 2**53
(Bug#36940#94).  This fixes the problem for Emacs 27 and later,
and doesn't hurt in earlier Emacs.
