We should use deferred loading not only for sRGB, but for
all standard profiles in the JRE. In particular case of the
jpeg plugin we are interested primarily in GRAY and PYCC profiles,
but there is no reason why the deferral loading can not be used
for CIEXYZ and linear RGB as well.
This change does not introduce any difference in the jre
behavior (except deferral profile data loading) if all
standard profiles are correctly installed in the jre:
any profile-related activity (like a color conversion,
profile data accesses and etc.) triggers profile activation.
