Fix false Dialyzer warnings for erl_tar:table/1
'tar_entry()' values are only returned if we specify the 'verbose'
option when calling table/2, which table/1 doesn't do.
Now, it appears that Dialyzer as of OTP 20 is clever enough to realize
that the return type of table/1 must intersect with the return type of
table/2, and so it ignores the fact that table/1 says it returns
strings, and therefore its callers are expected to be dealing with
'tar_entry()' tuples, and never with strings.
This is obviously a mismatch between what the code does and what the
spec says is does, leading to false Dialyzer warnings on code that uses
table/1 (and, presumably, also table/2 when called without
the 'verbose' option.)
