Christian Brauner 2a4d517681 binfmt_elf: consume a stashed PT_INTERP substitute ...

When a binfmt_misc loader entry stashed bprm->loader use it instead of
opening the path named in PT_INTERP. The substitution deliberately
changes as little as possible. Ownership transfers into the local
interpreter reference which the existing success and error paths already
release.

A binary without PT_INTERP has nothing to substitute for. Drop the
override at the end of the segment scan and load the binary natively.

Nothing sets bprm->loader yet.
