cat-file: do not die on --textconv without textconv filters

When a command is supposed to use textconv filters (by default or with
"--textconv") and none are configured then the blob is output without
conversion; the only exception to this rule is "cat-file --textconv".

Make it behave like the rest of textconv aware commands.
