[Build] fix md5sum calculation of web packages if transient error (#1…

…3013)

Fix #12279

Why I did it
Curl can fail when we calculate md5sum of web package.
E.g. if server responsed with 503 error.
But we don't validate this and pass any output from curl directly to md5sum.
After that we save incorrect md5 hash to versions-web file.

How I did it
use option --retry 5 for transient errors (default value is 0)
use option -f for curl and set -o pipefail for shell to detect errors
stop build if curl failed
