Add: Append needed path to LD_LIBRARY_PATH

Some cases are failed because their shared libraries are not found in
the snap shell with classic image. For instance, the command "vainfo"
and "edac-util" encounter this problem.

The proper way to solve this issue is appending the path to the
LDILIBRARY_PATH environment variable.

The test result of va-api and edac test cases on aaeon-tgl 22.04 Desktop (Beta):
https://certification.canonical.com/hardware/202110-29509/submission/292417/test-results/

We won't encounter the following issues in this fix
- edac/detect
  - "edac-util: error while loading shared libraries: libedac.so.1: cannot open shared object file: No such file or directory"

- va-api/va-initialize
  - "vainfo: error while loading shared libraries: libva-x11.so.2: cannot open shared object file: No such file or directory"

@Patrick,
Please also validate on 20.04 desktop image, send an MR to branch series_classic20 if this change is also required, thank you.

review: Approve

The paths of shared library are allocated properly in Focal Desktop image. Therefore, no need to do this patch on series_classic20 branch.
