Fix: examples make distcheck failure

"make distcheck" marks each source file on the srcdir in the extracted
dist tarball read-only. The examples copy from the srcdir into the
builddir before running the "make" examples, but this keeps the
read-only flag on the builddir directories, which fails the build
because the resulting objects cannot be created.

Fix this by ensuring the copied target directory for each example is
user-writeable.
