Hi, Maxim!

thanks for the patch!

From: Maksim Tiushev <mandesero@gmail.com>

This patch enables running tests with Valgrind. Custom Valgrind testing
options can be configured by setting the `VALGRIND_OPTIONS` variable.
Please note that this environment variable must be set before building,
and any updates to it will require a project rebuild. By default, the
suppression file is set to `src/lj.supp`.

Also this patch disables the following tests when running with Valgrind
due to failures:

For SIGPROF:

s/SIGPROF/sysprof/?

  - test/tarantool-tests/gh-7264-add-proto-trace-sysprof-default.test.lua
  - test/tarantool-tests/lj-512-profiler-hook-finalizers.test.lua
  - test/tarantool-tests/lj-726-profile-flush-close.test.lua
  - test/tarantool-tests/misclib-sysprof-lapi.test.lua

For TIMEOUT:

It is not clear what do you mean with "for TIMEOUT".

Whether these tests timed out due to running under Valgrind or not?

  - test/tarantool-tests/gh-7745-oom-on-trace.test.lua
  - test/tarantool-tests/lj-1034-tabov-error-frame.test.lua

I think we need followup issues for these tests and put a link to the issue to the

commit message. Otherwise, these tests will remain unfixed. It is desirable to

describe details of failures under Valgrind in that issue.

I would add a number of the issue instead.
