cmake: support for testing git when building out of the source tree

This patch allows git to be tested when performin out of source builds. This involves changing GIT_BUILD_DIR in t/test-lib.sh to point to the build directory. Also some miscellaneous copies from the source directory to the build directory. The copies are: t/chainlint.sed needed by a bunch of test scripts po/is.po needed by t0204-gettext-rencode-sanity mergetools/tkdiff needed by t7800-difftool contrib/completion/git-prompt.sh needed by t9903-bash-prompt contrib/completion/git-completion.bash needed by t9902-completion contrib/svn-fe/svnrdump_sim.py needed by t9020-remote-svn NOTE: t/test-lib.sh is only modified when tests are run not during the build or configure. The trash directory is still srcdir/t Signed-off-by: Sibi Siddharthan <sibisiddharthan.github@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
