    Fix DLL export forwarding

    I noticed it when I was trying to set a breakpoint at ExitProcess:
    ```
    (gdb) b ExitProcess
    Breakpoint 1 at 0x14001fdd0
    (gdb) r
    Starting program: C:\qiewer\heob\heob64.exe
    Warning:
    Cannot insert breakpoint 1.
    Cannot access memory at address 0x3dbf4120
    Cannot insert breakpoint 1.
    Cannot access memory at address 0x77644120
    ```

    The problem doesn't exist in gdb 13.2, and the difference can easily be
    seen when printing ExitProcess.
    gdb 14.1:
    ```
    (gdb) p ExitProcess
    $1 =3D {<text variable, no debug info>} 0x77644120
<UserHandleGrantAccess+36128>
    ```
    gdb 13.2:
    ```
    (gdb) p ExitProcess
    $1 =3D {<text variable, no debug info>} 0x77734120 <ntdll!RtlExitUserPr=
ocess>
    ```

    The new behavior started with 9675da25357c7a3f472731ddc6eb3becc65b469a,
    where VMA was then calculated relative to FORWARD_DLL_NAME, while it was
    relative to DLL_NAME before.

    Fixed by calculating VMA relative to DLL_NAME again.
