lvm2: replace !BR2_PACKAGE_LVM2_DMSETUP_ONLY by BR2_PACKAGE_LVM2_STANDARD_INSTALL

BR2_PACKAGE_LVM2_DMSETUP_ONLY is a "negative" option that disables
build and install of part of the suite. This option cannot be unselected
by other config options, which gives a problem for BR2_PACKAGE_UDISKS_LVM2:
it needs BR2_PACKAGE_LVM2_APP_LIBRARY, which requires the full suite.

Therefore, replace the negative BR2_PACKAGE_LVM2_DMSETUP_ONLY by a positive
BR2_PACKAGE_LVM2_STANDARD_INSTALL. To make sure that existing defconfigs
keep working, the new option defaults to y unless the legacy
BR2_PACKAGE_LVM2_DMSETUP_ONLY was selected.

Fixes http://autobuild.buildroot.net/results/ea4627cae45e972ebba5b33a2b2871ce7f46fedc/
