Sync proc_service definition with GLIBC

Browse source 
GLIBC BZ#20311 [1] proc_service.h install patch also remove 'const'
attributes from ps_get_thread_area and comment #15 discuss why to remove
the const attribute (basically since it a callback with the struct
ps_prochandle owned by the client it should be able to modify it if
it the case).

On default build this is not the issue and current g++ does not trigger
any issue with this mismatch declaration.  However, on some bootstrap
build configuration where gdbserver is build with gcc instead this
triggers:

error: conflicting types for 'ps_get_thread_area'

This patch fixes it by syncing the declaration with GLIBC.
