Prevent cqfd from globbing release files before the build

[Ballasi]

The following code:

https://github.com/savoirfairelinux/cqfd/blob/46ea5bc458dec354a5a5cce2e3c8dde51b2fe5c2/cqfd#L382

causes a potential glob of the cqfd release files to happen, in the config_load() function, i.e., before the build command has been started.

If a file has already been built previously, and contains a name that can be different from a build to another (for instance because it contains the build date, the git description, ...), it therefore may break on cqfd release calls as it tries to glob the filename with the previous name.

Here is an example environment that reproduces this bug:

.cqfdrc

[project]
org='org'
name='name'

[build]
command='rm -f file_* && touch file_$(cat /dev/urandom | tr -dc 'A-Za-z0-9' | fold -w 8 | head -n 1)'
files='file_*'

.cqfd/docker/Dockerfile

FROM ubuntu:20.04
ENV DEBIAN_FRONTEND noninteractive
