Subject: [PATCH 1/2] gfile: Factor out flags when copying files
This introduces no functional changes; just reduces duplication in the
code a little.

If a copy operation is started with `G_FILE_COPY_TARGET_DEFAULT_PERMS`,
don’t create the destination file as private. Instead, create it with
the process’ current umask (i.e. ‘default permissions’).
This is a partial re-work of commit d8f8f4d637ce43f8699ba94c9b, with
input from Ondrej Holy.

Fixes: #174
