Subject: [PATCH] Fix crash running in restricted environment.

When `pwd.h` header is not available (i.e. not using glibc) and environment
variables are not set (e.g. running via `env --ignore-environment`) client
library would crash due to uninitialized variable in `pa_get_home_dir()`.
Add missing initialization to fix that.

Fixes: #3792
