checksec needs the readelf command to work properly, which is contained
in the binutils-unwrapped derivation but not in the normal binutils.
Before this commit, this tool wasn't working due to that.
* treewide: http -> https sources
This updates the source urls of all top-level packages from http to
https where possible.
* buildtorrent: fix url and tab -> spaces
readelf which makes most of checks should come from binutils package instead of elfutils
E.g. the PIE check from checksec, different readelf gives different result:
(elfutils)
$ /nix/store/rgrji20513g19ci0sa6jydm86gpf4j42-elfutils-0.158/bin/readelf -d /nix/store/q1sbn93v4k3166s091s9biygv9srv8qa-nginx-1.6.2/bin/nginx
2>/dev/null |grep -q '(DEBUG)' ; echo $?
1
(binutils)
$ /nix/store/b8qhjrwf8sf9ggkjxqqav7f1m6w83bh0-binutils-2.23.1/bin/readelf -d /nix/store/q1sbn93v4k3166s091s9biygv9srv8qa-nginx-1.6.2/bin/nginx
2>/dev/null | grep -q '(DEBUG)' ; echo $?
