Add conditional profile loading

Browse source 
Normally, inclusion of any profile that is not found in profile
directories (/etc/tuned and /usr/lib/tuned) will fail at profile
application time.

Conditional profile loading can be useful in situations we do not
necessarily expect a certain included profile to exist.  Profile
application failures are undesirable in such cases.  Augment the
TuneD profile hierarchies by adding a functionality to conditionally
include a profile by prefixing its name by '-' symbol.

Example:
[main]
summary=An example TuneD profile demonstrating conditional loading
include=-profile1,profile2

In this example, the profile "profile1" is conditionally loaded/included
and no error/failure will be reported if the profile does not exist.
Then, the profile "profile2" is unconditionally loaded and errors will be
reported if it is not found in profile directories.
