BaseTools: InfBuildData: Fix Private dec data retrieval (#785)

## Description

Private package dec sections (such as guids [Guids.Common.Private], Ppis
[Ppis.Common.Private], and protocols [Protocols.Common.Private]) become
inaccessible for components of the same package if the module's EFI_GUID
value is overwritten (Which is commonly done to build the same module
multiple times with different settings)

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4730

- [ ] Impacts functionality?
- **Functionality** - Does the change ultimately impact how firmware
functions?
- Examples: Add a new library, publish a new PPI, update an algorithm,
...
- [ ] Impacts security?
- **Security** - Does the change have a direct security impact on an
application,
    flow, or firmware?
  - Examples: Crypto algorithm change, buffer overflow fix, parameter
    validation improvement, ...
- [ ] Breaking change?
- **Breaking change** - Will anyone consuming this change experience a
break
    in build or boot behavior?
- Examples: Add a new library class, move a module to a different repo,
call
    a function in a new library class in a pre-existing module, ...
- [ ] Includes tests?
  - **Tests** - Does the change include any explicit test code?
  - Examples: Unit tests, integration tests, robot tests, ...
- [ ] Includes documentation?
- **Documentation** - Does the change contain explicit documentation
additions
    outside direct code modifications (and comments)?
- Examples: Update readme file, add feature readme file, link to
documentation
    on an a separate Web page, ...

## How This Was Tested

Verified private guids continue to be accessible to modules in the same
package, even when the EFI_GUID is changed in the dsc.
