perf probe: Allow to use filter on --del command
This makes perf-probe --del option to accept filter rules
not only simple glob pattern. This simplifies the code and
improve the flexibility.
E.g. if we remove 2 different pattern events, we need 2
-d options.
----
# ./perf probe -d vfs\* -d malloc
Removed event: probe_libc:malloc
Removed event: probe:vfs_read
----
This allows you to joint the 2 patterns with '|'.
----
# ./perf probe -d 'vfs*|malloc'
Removed event: probe:vfs_read
Removed event: probe_libc:malloc
