Make the empty headers used by cl-pch-showincludes.cpp unique so that filesystems that link these files together by contents will not see different behaviour in this test, which is not testing linked files specifically.

This was uncovered by 5ea78c4113f8 <https://reviews.llvm.org/rG5ea78c4113f8d2c8be24152f2dd0cadaea352c9d> which made us stop mutating the name of the presumed loc for the file in ContentCache, but that just surfaced an underlying issue that the filename of multiple includes of linked files are not separately tracked.
