tcl: Install header into 8.6 instead of PN-PV in user/include

tcl: Install header into 8.6 instead of PN-PV in user/include

This helps in compiling other programs like expect which
depend on private headers but 8.5, 8.6 and so on is enough
granularity and currently we had 8.6.x and so on which
means that expect recipe will need to be touched whenever there
is minor update of tcl.

Additionally the encode creating symlink to shared object in
patch and remove it from recipe

Refresh patches after making changes to Configure.in we
propertly generate configure and not patch is directly as
was the case.
