[Replicant] [vendor_replicant][PATCH] sign-build.sh: fix unexpected operator with multiple TARGET_FILES

[Denis 'GNUtoo' Carikli]

sign-build sometimes fails when there is multiple files
matching the *-target_files-*.zip pattern for TARGET_FILES:
when checking if TARGET_FILES is a file with
[ -f $TARGET_FILES ], it can fail because -f expects ai
single path.

When it happens the failure looks like that:
  vendor/replicant/sign-build: 111: [:
  [...]/out/target/product/maguro/obj/PACKAGING/target_files_intermediates/replicant_maguro-target_files-3c9b1e0289.zip:
  unexpected operator

The TARGET_FILES files we are sigining in sign-build.sh
have their build rules in build/core/Makefile where the
resulting path of the file is defined in this way:
  BUILT_TARGET_FILES_PACKAGE := $(intermediates)/$(name).zip
name is in turn defined like this:
  name := $(name)-target_files-$(FILE_NAME_TAG)
and FILE_NAME_TAG like this:
  FILE_NAME_TAG := $(BUILD_NUMBER)

Since we have access to the device name and the
BUILD_NUMBER that is used to construct the FILE_NAME_TAG,
we can use them to find out the name of the file to sign
instead of relying on fragile glob ('*') patterns.
