Update pathname resolution behavior for trailing slashes to match POSIX specifications

POSIX says, for pathname resolution, that:
"A pathname that contains at least one non- <slash> character and that ends with one or more trailing <slash> characters shall not be resolved successfully unless the last pathname component before the trailing <slash> characters names an existing directory or a directory entry that is to be created for a directory immediately after the pathname is resolved. "

AIX (7.1 and 7.2 tested) allow trailing slashes on filenames:

/bin/ksh/ -c 'echo hi'


ls -l /bin/ksh /bin/ksh/
-r-xr-xr-x 5 bin bin 313906 Nov 28 2017 /bin/ksh
-r-xr-xr-x 5 bin bin 313906 Nov 28 2017 /bin/ksh/
further specifies, in A.4.13 Pathname Resolution, in part:

"Pathnames that end with one or more trailing <slash> characters must refer to directory paths. Earlier versions of this standard were not specific about the distinction between trailing <slash> characters on files and directories, and both were permitted."
