gdbserver/linux-aarch32-low: build failure when NT_ARM_VFP not defined

On some older versions of GNU/Linux, gdbserver now fails to build
due to an undefined reference to NT_ARM_VFP. Same issue on Android,
where this macros is undefined until Android API level 21 (Android
5.0 "Lollipop").

This patch modifies linux-aarch32-low.c to define that macros when
not already defined.

gdb/gdbserver/ChangeLog:

        * linux-aarch32-low.c (NT_ARM_VFP): Define if not already defined.
