helper: fix build with mingw gcc 12.1.0

New mingw compiler correctly complains for using a freed memory
area:

src/helper/configuration.c: In function 'get_home_dir':
src/helper/configuration.c:182:29: error: dangling pointer 'home'
to 'homepath' may be used [-Werror=dangling-pointer=]
182 | home_path = alloc_printf("%s/%s", home, append_path);
    |             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In fact the variable 'homepath' is declared inside an 'if' branch
and is not available outside.

Move the declaration of 'homepath' to have it available in a wider
context.
