tcl: Add ${bindir_crossscripts}/tclConfig.sh to sysroot stage
tclConfig.sh is changed in do_install for cross compile and
is installed to STAGING_BINDIR_CROSS, but if SSTATE_DIR is set
and tcl is from sstage, tclConfig.sh can't be found in
STAGING_BINDIR_CROSS, add ${bindir_crossscripts}/tclConfig.sh
to sysroot stage can fix it.
