C standard claims "An object declared as type _Bool is large enough to
store the values 0 and 1", bool type size can be 1 byte or larger than
1 byte. Thus it's uncertian for bool type size with different
compilers.
This patch changes the bool type in structure perf_record_time_conv to
__u8 type, and pads extra bytes for 8-byte alignment; this can give
reliable structure size.
Fixes: d110162cafc8 ("perf tsc: Support cap_user_time_short for event TIME_CONV")
