Subject: test: increase ext4 size in build_ext4_image
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=527d4b5abf55076300661b638082e2ec8ddce349;p=thirdparty%2Fdracut-ng.git

test: increase ext4 size in build_ext4_image

Adding a fixed amount of 10 MB to the ext4 image size might not be
enough (for example when using `build_ext4_image` in test 60).

So calculate the additional size by a percentaged and a fixed amount.
