perf record: Remove newline character from perror() argument

If we include a newline character in the string argument to perror()
then the output will be split across two lines like so,

    Unable to read perf file descriptor
    : No space left on device

Deleting the newline character prints a much more readable error,

    Unable to read perf file descriptor: No space left on device
