tests: verify that halcompile installs files with correct permissions

JT reports on IRC that `halcompile --install` installs uspace realtime
comps (which are .so files) with execute permissions enabled, which
is wrong.

This commit modifies some existing halcompile tests to verify that
`halcompile --install` makes userspace (non-rt) comps executable, and
rt comps (at least in uspace) non-executable.

The second part of that currently fails, fixed in the following commit.

(Note that our debs correctly have no execute bits set for the .so
realtime comps.)
