[lld] r329271 - [ELF] - Print LMA in a -Map file.

The widths of LMA and Size are not correct as you can see below.
VMA LMA Size Align Out In Symbol
2002a8 2002a8 1c 1 .interp
VMA and LMA need to be the same width because they are the same, and we
don't need that large space for Size for a obvious reason. So the correct
output should be like this.
VMA LMA Size Align Out In Symbol
2002a8 2002a8 1c 1 .interp
I'll fix this.
