Remove special handling of frameworks/base/config/boot-profile.txt

Previously, the method was run in repo manifests that did not include
the frameworks/base repository so it had to handle the file being
missing. However, now that this is being called from
platform_bootclasspath which is only defined in frameworks/base that
is no longer required.
