IT FIM - Fix Solaris and Macos fails for 4.3

[Deblintrake09]

Related issues	#2881

Description

During runs of the Nightly pipeline, it was found that the test module test_basic_usage_realtime_unsupported.py was having flaky behaviour, on Solaris OS. This PR applies a fix to that test, as well as two other modules that also presented flaky behaviour during testing.

Also, during testing it was found that the modify_file_inode function on the deps/wazuh_testing/fim.py module would cause OS ERROR 18: Invalid cross device link on some systems, because of the function os.replace. The function was replaced by shutil.move, that has the same functionality and parameters but does not generate this error.
