RFR(XS): 8047154: Testset all fails because of missing jdk_beansX test groups

[Mikael Vidstedt]

Please review -- the jdk_beansX targets were removed as part of moving 
from Makefile logic to jtreg test groups late last year and the "all" 
testset currently fails because of that. The only remaining beans group 
is called jdk_beans and this change reflects that change.
