cve-check-tool: Add recipe

cve-check-tool is a program for public CVEs checking.
This tool also seek to determine if a vulnerability has
been addressed by a patch.

The recipe also includes the do_populate_cve_db task
that will populate the database used by the tool.

+Subject: [PATCH] Check for malloc_trim before using it
+
+malloc_trim is gnu specific and not all libc
+implement it, threfore write a configure check
+to poke for it first and use the define to
+guard its use.
+
+Helps in compiling on musl based systems
