Subject: [PATCH AUTOSEL 6.14 42/44] ktest: Fix Test Failures Due to Missing LOG_FILE Directories

From: Ayush Jain <Ayush.jain3@....com>

[ Upstream commit 5a1bed232781d356f842576daacc260f0d0c8d2e ]

Handle missing parent directories for LOG_FILE path to prevent test
failures. If the parent directories don't exist, create them to ensure
the tests proceed successfully.
