[clang] [Serialization] Remove an unused local variable (NFC) (PR #141358)

[Kazu Hirata via cfe-commits]

https://github.com/kazutakahirata created https://github.com/llvm/llvm-project/pull/141358

Note that getTimestampFilename just constructs a file name, so it's
mostly a "pure" function except possible heap allocation.
