test: Minor fix in test - locale in terminal #28286

1. 
   crywolf commented at 5:24 pm on August 17, 2023: none

   Running tests with non-English locale set in Linux terminal makes system tests (system_tests/run_command) fail. Setting the locale in failing test explicitly to ‘C’ fixes the failure.

   How to reproduce test failure: Setting LC_ALL=cs_CZ.UTF-8 (export LC_ALL=cs_CZ.UTF-8) in terminal and then running make check should be enough.

   Fix: My terminal is by default set to non-English locale and the test failed because it checks for English error message, but the terminal produces error message in the language set by locale. Then I manually set export LC_ALL=C in my terminal and all tests passed. So I explicitly set env variable ‘LC_ALL’ to ‘C’ in the code of failing test.

   Running tests with non-English locale set in Linux terminal makes system tests (system_tests/run_command') fail.
   Setting the locale env variable 'LC_ALL' in failing test explicitly to 'C' fixes the failure.

   During the workshop wit Gloria @glozow on Dev/Hack/Day (part of BTC Prague conference) my tests failed. Later that day I found what the problem was and now I am finally presenting my fix as an attempt to make my first PR in this repo.

   Concept ACK, though I’m unable to reproduce this on macOS, which makes sense per src/common/system.cpp#L66-73:

   0    // On most POSIX systems (e.g. Linux, but not BSD) the environment's locale
   1    // may be invalid, in which case the "C.UTF-8" locale is used as fallback.
   2#if !defined(WIN32) && !defined(MAC_OSX) && !defined(__FreeBSD__) && !defined(__OpenBSD__) && !defined(__NetBSD__)
   3    try {
   4        std::locale(""); // Raises a runtime error if current locale is invalid
   5    } catch (const std::runtime_error&) {
   6        setenv("LC_ALL", "C.UTF-8", 1);
   7    }

    lgtm, but if the file exists, this will also fail.

    Might be better to use a pure command that does not depend on the env vars and filesystem state

    Apologies for the slow review on this, and it eventually going stale. I’ll close for now, but the issue will still need a fix. Ideally like #28286 (review)

    Anyone is welcome to open a new pull request with the fix.
