description:
Fix the trailing space in the probe specifier's name in dtrace(1)'s output.

When using dtrace using one of the tracing options, such as -n, -P, -i, -f etc.,
the first line of output from dtrace one is something like this:

sudo dtrace -n 'syscall:::entry /pid == 100/ {@num[probefunc] = count();}'
dtrace: description 'syscall:::entry ' matched 482 probes

There is a trailing space at the end of the probe specifier name ('syscall:::entry ').
This happens beucase dtrace tries to separate the probe name from the predicate and actions
using `{' and `/' as the separators but doesn't consider space also as a possible separator.

Output after this change:
sudo dtrace -n 'syscall:::entry /pid == 100/ {@num[probefunc] = count();}'
dtrace: description 'syscall:::entry' matched 482 probes
