Rename target.linux[_x86[_64]] to target.linux_glibc[_x86[_64]]

In the future, target.linux will apply to all targets running a linux kernel
(android, linux_glibc, linux_bionic). So move all current users to the specific

There will be another cleanup pass later that will move some instances back to
target.linux if the properties should be shared with and
target.linux_bionic, but target.linux needs to be removed first.
