Subject: [PATCH] kernel-image: handle errors when reading the .osrel section

uki_read_pretty_name() only handles a missing .osrel section. Any other
error, for example an .osrel section larger than PE_SECTION_READ_MAX,
passes a NULL buffer to parse_env_data(), and "bootctl kernel-inspect"
aborts:

    Assertion 'data' failed at src/basic/env-file.c:429

Return the error instead.

(cherry picked from commit 37717744394b433eb452674f060a4288a8f469bf)
