[gdb/symtab] Support DW_AT_main_subprogram with -readnow.
DW_AT_main_subprogram is supported in normal mode in read_partial_die, but not
in -readnow mode.
Fix this by adding support for DW_AT_main_subprogram in read_func_scope.
Tested on x86_64-linux with native and RFC target board readnow (
https://sourceware.org/ml/gdb-patches/2019-05/msg00073.html ).
