Trace only system calls accessing path

-P path option is used to set only tracing system calls which access the specified path. E.g.:

# strace -P /etc/ld.so.preload ls
access("/etc/ld.so.preload", R_OK)      = -1 ENOENT (No such file or directory)
+++ exited with 0 +++

Only access system call is tracked.
