Fix build flake on box2d port.

Cmake seems to have problems building multiple targets in parallel (it spawns

Add missing import to sha1sum.py.

Direct errors to stderr (since the normal operation of this
script is to redirect stdout, errors were being hidden).

Don't catch generic Exception.

Don't allow empty .sha1 files when checking sums.

Rename naclports packages not to include version.

This change renames the directories containing packages
to that they do not contain version numbers.  It also
renames the .sh build script and the .patch files likewise.
The rational here is that:
 a) its redundant information
 b) it makes it hard to navigate the tree and run scripts.
    (./libraries/lua/nacl-lua.sh is much easier to type
     than ./libraries/lua-5.4.1/nacl-lua-5.4.1.sh)
 c) its makes it hard to roll package versions (you need to
    rename folders and then rename files within them
    to bump a version)

One downside is that it becomes messier when you want to
package two versions of the same library.  This would then
be and exception to the rule when a version could be
included in the package name (similar to how it is done
for deb packages).
