Bit more test data, this time with complete info copied, mainly with
cache information, so we can easily add tests for it.

The AMD Bulldozer architecture uses so called "Clustered integer core
modules" that count both as threads and cores. This patch expects the
cpu to be detected using the new fallback condition otherwise twice the
number of processors would be detected.

The test data contained extra \0 bytes after newlines probably due to a
kernel off-by-one bug.

Commit ddd6bef4 switched to the ustar format to fix an issue where
'make dist' fails to create a tarball because we have files with
relative names longer than 100 bytes by the time you include a
'libvirt-0.9.13' prefix.  Unfortunately, even with ustar format,
the use of 'tar -ch' tries to convert symlinks to hard links,
also with a name too long (omitting the -h works, but automake
automatically passes -h); such symlinks were added in commit
6dcf98c8, which resulted in 'make dist' breaking again.  The
solution is to rename the offending symlinks to something shorter,
by shortening the entire nodeinfodata naming scheme.

* tests/nodeinfotest.c (mymain): Shorten test names.
(linuxTestNodeInfo): Accommodate new names.
* tests/nodeinfodata/*: Rename files accordingly.

This patch adds test data needed by the new way node information will be
gathered. This patch adds symlinks to cpu cores to their corresponding
node directory.

Test 2 data grabbed from a 2-core 1-node laptop.
Test 3 data grabbed from a 48-cpu AMD Magny Cours box.

* tests/nodeinfodata/linux-nodeinfo-sysfs-test-2*: New test data.
* tests/nodeinfodata/linux-nodeinfo-sysfs-test-3*: Likewise.
* tests/nodeinfotest.c (mymain): Run them.
* cfg.mk
(exclude_file_name_regexp--sc_prohibit_empty_lines_at_EOF): Exempt
new test files.
