Alias sys_mkdir and sys_mkdirat to sys_chmod and sys_fchmodat

Special parsers for mkdir and mkdirat are redundant because
sys_chmod and sys_fchmodat implement the same decoding.

* file.c (decode_mkdir, sys_mkdir, sys_mkdirat): Remove.
* linux/dummy.h (sys_mkdir): Alias to sys_chmod.
(sys_mkdirat): Alias to sys_fchmodat.
* linux/syscall.h (sys_mkdir, sys_mkdirat): Remove.
* pathtrace.c (pathtrace_match): Do not check for sys_mkdirat.
