Imagine we have:

  ProgramHeaders:
    - Type:  PT_LOAD
      Flags: [ PF_W, PF_R ]
      Sections:
        - Section: .bar
      VAddr: 0x2000
  Sections:
    - Name:    .foo
      Type:    SHT_PROGBITS
      Flags:   [ SHF_ALLOC, SHF_EXECINSTR ]
      Address: 0x1000
    - Name:    .bar
      Type:    SHT_PROGBITS
      Flags:   [ SHF_ALLOC, SHF_EXECINSTR ]
      Address: 0x2000

Both `.foo` and `.bar` share the same starting file offset,
but `VA(.foo)` < `VA(PT_LOAD)`, we should not include it into segment.

This patch fixes the issue.
