Avoid 1 case of holding a semaphore while mmap callbacks are being made.
* runtime/task_finder.c (__stp_call_mmap_callbacks_with_addr): Renamed
from __stp_call_mmap_callbacks_with_vma(). Also added some code from
__stp_utrace_task_finder_target_syscall_exit() that locks the 'mmap_sem'
semaphore. This avoids holding the semaphore while the mmap callbacks
are made.
(__stp_utrace_task_finder_target_syscall_exit): Just calls
__stp_call_mmap_callbacks_with_addr() in the mmap case.
