[lit] Add HOME to "safe" variables to pass through to tests

mgorny · mgorny · commit 763e7fb5b28f · 2025-05-10T11:36:15.000+02:00
Incldue `HOME` among the variables that are passed through to tests
when environment is cleaned. This is necessary for Gentoo build
environments, where individual package builds are given temporary
home directories that are exposed via `HOME` variable. By stripping
the variable, `lit` made these tests attempt to access user's home
directory, resulting in permission errors.
