perf script: Allow --symbol to accept hexadecimal addresses

perf script: Allow --symbol to accept hexadecimal addresses

This patch extends the perf script --symbols option to filter on
hexadecimal addresses in addition to symbol names. This makes it easier
to handle cases where symbols are aliased.

With this patch, it is possible to mix and match symbols and hexadecimal
addresses using the --symbols option.

  $ perf script --symbols=noploop,0x4007a0
