ci: switch build scripts from wget to curl

runc's build scripts and CI setup used a mix of wget (4 sites) and
curl (8 sites) for HTTPS fetches. Standardise the three script sites on
curl, which is already required by the majority of call sites.

* script/build-libpathrs.sh and script/build-seccomp.sh: replace
  wget "<url>"{,.asc} with curl -fsSLO "<url>"{,.asc}. Bash brace
  expansion still yields two separate downloads (the tarball and its
  .asc signature).
* script/setup_host.sh: replace wget with curl in the Fedora RPM
  install list.

Leaving the single wget call in Dockerfile untouched per review
feedback -- the trixie base image already ships wget, and switching
would add an extra apt-get update && install step before the existing
single-pass package install.
