dracut: upgrade 055 -> 056

* Add a patch to fix musl build:
  src/install/util.c:30:19: error: missing binary operator before token "("
     30 | #if __GLIBC_PREREQ(2, 30) == 0
        |                   ^
  make: *** [Makefile:57: src/install/util.o] Error 1

* Pass "-fPIC" to CFLAGS to fix build warning with musl build:
  WARNING: dracut-1_056-r0 do_package_qa: QA Issue: dracut: ELF binary
  /usr/lib/dracut/dracut-install has relocations in .text [textrel]
