[LTP] [PATCH] Remove files which does not have a dmesg entry

[Subrata M. <su...@li...>]

Hi,

The recently introduced option:

-K DMESG_LOG_DIR
	Log Kernel messages generated for each test cases inside this directory,

when used will generate huge no. of files inside the DMESG_DIR. Many of
them will be ZERO size as we do not expect KERNEL MESSAGE to be generated
against all the LTP TESTS that we will run. It is better to prune them, and
let only those files exist which will have real entries. The following
patch fixes the same.
