tk: Remove buildpath issue

Though the S defined as ${WORKDIR}/${BPN}${PV}/unix, but some source
files come from such as ${WORKDIR}/${BPN}${PV}/unix/../generic, so add
"-fdebug-prefix-map=${S}/../" to fix the below buildpath issue:
  WARNING: tk-8.6.10-r0 do_package_qa: QA Issue: File /usr/lib64/.debug/libtk8.6.so in package tk-dbg contains reference to TMPDIR
  File /usr/bin/.debug/wish8.6 in package tk-dbg contains reference to TMPDIR [buildpaths]
