[meta-multimedia][PATCH] libcamera: build with 64-bit time_t

[prasanth]

64-bit time was turned off for all of libcamera because v4l2-compat.
libcamera fixed this upstream in v0.3.0 by also
undefining _TIME_BITS for v4l2-compat (commit 705601 "v4l2:
Unset _TIME_BITS in addition to _FILE_OFFSET_BITS"), so the
workaround is no longer needed.

v4l2-compat.so still uses 32-bit APIs on purpose, so keep the
32bit-time QA skip for it.

libcamera.so before:
  recvmsg@GLIBC_2.4, ioctl@GLIBC_2.4, clock_gettime@GLIBC_2.17,
  stat64@GLIBC_2.33, fstat64@GLIBC_2.33, sendmsg@GLIBC_2.4
after:
  __recvmsg64, __ioctl_time64, __clock_gettime64,
  __stat64_time64, __fstat64_time64, __sendmsg64 (GLIBC_2.34)
