package/stress: bump to version 1.0.5

Switch to an active fork:

"The original stress went unmaintained; the source of the last version,
1.0.4, was imported from Debian. After, patches from Debian and other
changes were applied to create the 1.0.5 release. The details of each
release are registered in the ChangeLog file. Now, stress is maintained
by volunteers under Resurrecting Open Source Projects."
