Subject: Use correct TLS codepath in graphics libraries

Duplicate ARCH_ARM_HAVE_TLS_REGISTER BoardConfig to proprocessor
HAVE_ARM_TLS_REGISTER define from Bionic's libc Android.mk to ensure that
OpenGL libraries (libEGL, libGLESv1_CM, libGLESv2, libGLES_android) use the
correct codepath in bionic_tls.h for accessing the TLS address
