tcl: fix the TCL_INCLUDE_SPEC

We have moved the header files to ${includedir}/tcl${VERSION}, but we
didn't fix the TCL_INCLUDE_SPEC which is still ${includedir}, it should
also be ${includedir}/tcl${VERSION}

Note: this commit modifiey alter-includedir.patch, so it doesn't look
very clear, I only fixed one line in both configure and configure.in:

-eval "TCL_INCLUDE_SPEC=\"-I${includedir}\""
+eval "TCL_INCLUDE_SPEC=\"-I${includedir}/tcl${VERSION}\""

The other changes are because I use git to create the patch while the
previous one uses svn.

[YOCTO #5732]
