package/flashrom: bump to final 1.4.0 release

This commit is suitable for master because:

$ git log --format=oneline v1.4.0-rc2..v1.4.0
eace095b15eb034e42d97202cad70ce979d8ca38 VERSION: Update version to 1.4.0
30c85a62c1abe07d57d5a7b523ef62c2c5b825c9 doc: Release notes for version 1.4.0
e4e0fd0d8232260af052fde52a9fb636181b2e2e meson: Fix project name as flashrom

And it looks nicer to have a final 1.4.0 release than a 1.4.0-rc2
release candidate.
