live555: fix library installation

The manual target installation commands optionally copy 3 executables
that demonstrate the library usage, but do not the library itself.

This results in the following errors at runtime:

  # openRTSP
  openRTSP: can't load library 'libliveMedia.so.38'
  # live555MediaServer
  live555MediaServer: can't load library 'libliveMedia.so.38'
  # MPEG2TransportStreamIndexer
  MPEG2TransportStreamIndexer: can't load library 'libliveMedia.so.38'
  #

Tested with the following defconfig, which is basically
qemu_arm_versatile_defconfig plus C++ and live555:

BR2_arm=y
BR2_KERNEL_HEADERS_VERSION=y
BR2_DEFAULT_KERNEL_VERSION="4.0"
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_4_0=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_TARGET_GENERIC_GETTY_PORT="ttyAMA0"
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_VERSION=y
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="4.0"
BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="board/qemu/arm-versatile/linux-4.0.config"
BR2_LINUX_KERNEL_ZIMAGE=y
BR2_PACKAGE_LIVE555=y
BR2_TARGET_ROOTFS_EXT2=y

Fix the whole installation step by using the 'make install' step provided
by the upstream package, similar to what was done in commit
44d15563c706dce48f84 for the staging installation.

Note: this change has the effect of installing unconditionally all the
test and demo executables produced by the live555 compilation process,
and that were previously not (or optionally) copied. This increases the
uncompressed target filesystem size by roughly 300 kB (tested for a
32-bit ARM target). Undesired files can be deleted in a post-build script.
