remove unused 'is an exported alias' message (re: 80d9ae2b)

Browse source 
Commit 80d9ae2b removed the line that set the NV_EXPORT flag on an
alias when the obsolete ksh88 'alias -x' option was used. But it
turns out that flag actually did something: it caused 'whence -v'
to report the alias as an exported alias -- misleadingly, because
exported aliases have never actually exised in ksh93. Since '-x' no
longer sets that flag, that message is never printed.

src/cmd/ksh93/data/msg.c,
src/cmd/ksh93/include/path.h:
- Remove is_xalias[] = "%s is an exported alias for " message.

src/cmd/ksh93/bltins/whence.c:
- Remove dead code to check for (formerly) exported alias.
