test: decrease the source file size from 16MB to 12MB

[hzhuang1]

While decompress a compressed file, it's risky if the plain text file is 16MB. So downgrade it to 12MB.

with text file /tmp/syslog
double free or corruption (!prev)

Fail to run UADK tests with static build.

Actually it's not a right fix. It should be abandoned.

There're multiple reasons of this "double free" issue.

1. Because dladdr() is used, wd_get_lib_file_path() can't support to search static library path.
2. In dynamic library version, it also reports error in fill_zip_comp_sqe() with error code EINVAL.

I attached my script file to reproduce this issue much easier. "cc" was used to invoke either the static library test or dynamic library test. "sanity.patch" was used to apply on $UADK/test/sanity_test.sh. And I also used "syslog.1" as test file. You could find it from "/var/log/syslog.1" from the CI server.

Although the test file is huge, the real test file should be only 16MB. And this issue occurred in "hw_ifl_perf()" with block mode. Each block size is only 8KB. So this issue is not related to 16MB size or 12MB size. I think you guys are much familiar with the hardware. Please help to debug it.
