[tex-live] Error when running `tlmgr path remove` if docs are not installed

[Karl Berry]

      sh: line 0: cd: $TEXDIR/texmf-dist/doc/man: No such file or directory

Tried to fix in r45994, though I guess it won't show up until the next
time we push tlcritical to tlnet. You could just patch
tlpkg/TeXLive/TLUtils.pm by hand if you want to try it ... --thanks, karl.
