mediapc: Add precondition checks for few tests
Tests in PerformanceClassTest and VideoCodecRequirementsTest were
being run even when the device didn't meet minimum precondtions
for it to be a performance class candidate (eg: media performance
class tests are only applicable to handheld devices)
Also added an assertTrue() to ensure performance points are listed
for all h/w codecs.
