[PATCH] perf buildid-cache: update help text for purge command

[Thomas Richter <tmricht@linux.vnet.ibm.com>]

Clarify the perf buildid-cache help text for the purge operation.
The purge subcommand takes a list of files (binaries) as
option parameter. Make the wording the same as for the add
and remove operation.
