TJBench: Fix errors when decomp. files w/ ICC data

Browse Source 
Embedded ICC profiles can cause the size of a JPEG file to exceed the
size returned by tjBufSize() (which is really meant to be used for
compression anyhow, not for decompression), and this was causing a
segfault (C) or an ArrayIndexOutOfBoundsException (Java) when
decompressing such files with TJBench.  This commit modifies the
benchmark such that, when tiled decompression is disabled, it re-uses
the source buffer as the primary JPEG buffer.
