    Fix procfs.c compilation
    
    procfs.c doesn't compile on Solaris:
    
    /vol/src/gnu/gdb/hg/master/local/gdb/procfs.c: In member function ‘virtual bool procfs_target::info_proc(const char*, info_proc_what)’:
    /vol/src/gnu/gdb/hg/master/local/gdb/procfs.c:3302:3: error: ‘gdb_argv’ was not declared in this scope
     3302 |   gdb_argv built_argv (args);
          |   ^~~~~~~~
    /vol/src/gnu/gdb/hg/master/local/gdb/procfs.c:3303:20: error: ‘built_argv’ was not declared in this scope; did you mean ‘buildargv’?
     3303 |   for (char *arg : built_argv)
          |                    ^~~~~~~~~~
          |                    buildargv
    
    Fixed by including  "gdbsupport/buildargv.h".
    
    Tested on amd64-pc-solaris2.11, sparcv9-sun-solaris2.11.
