Fix temporary file name strlcpy size.
The strlcpy size argument overflows on integer sanitized builds.
runtime error: unsigned integer overflow: 11 - 35 cannot be represented
in type 'unsigned long'
This doesn't cause a problem because strlcpy stops on the null in
TMP_FILE_PATTERN, and localTmpFileName is defined large enough to
contain TMP_FILE_PATTERN.
This changes the size argument to the remaining length in the buffer,
and removes an extraneous '/' write as TMP_FILE_PATTERN already begins
with '/'.
Bug: 30969751
Test: Reran CTS test which triggered the overflow.
