tools/cmake: Update to 3.15.1

Update CMake to 3.15.1
Refresh patches
Remove inofficial fossies.org and replace with GitHub (link on official site)
Remove 150-C-feature-checks-Match-warnings-more-strictly.patch as it's
a no longer needed backport from upstream.
Disable ccache if GCC is 4.8, 4.9 or 5.X to avoid build failures.

-Subject: [PATCH] C++ feature checks: Match warnings more strictly
-
-Require the word "warning" to appear at the start of a line, after
-whitespace, or after a `:`.  This is the same that CTest launchers use
-to match warnings.  It avoids matching "warning" inside file paths.
-
-Fixes: #19019
